Posted by Sun Coating on | Comments Off on Does A Teflon Coat Resist Adhesives?
Adhesives don’t fail on Teflon by accident; it’s pure chemistry. In the manufacturing industry, this behavior can be both a challenge and a big advantage. When coatings, adhesives, or labels don’t stick where they shouldn’t, equipment remains cleaner, maintenance costs decrease, and line efficiency improves.
Polytetrafluoroethylene (PTFE), a synthetic fluoropolymer with remarkable non-stick properties, is marketed under the name Teflon. It is extensively utilized in industries that require dimensional stability under heat, chemical resistance, and dependable release characteristics.
However, what makes Teflon so resistant to adhesives? Its molecular structure, surface energy, and adhesion failure mechanisms must all be carefully examined in order to provide an answer. Knowing these characteristics allows manufacturers to choose materials more wisely, design equipment more effectively, and produce better results.
Why Teflon Is One of the Most Adhesive-Resistant Materials on Earth
Teflon’s fluorinated molecular structure and incredibly low surface energy are the two key elements that give it its adhesive resistance.
At the molecular level, PTFE is made up of a carbon backbone that is totally encased in fluorine atoms. One of the most stable bonds in organic chemistry is formed by fluorine’s strong electronegativity, resulting in a surface that is:
Non-polar and chemically inert.
Extremely smooth, with minimal surface irregularities.
Hydrophobic and oleophobic, resisting both water-based and oil-based adhesives.
There are hardly any locations for mechanical or chemical bonding on this surface. In contrast, Teflon has a surface energy of about 18 mN/m, whereas most adhesives need at least 40 mN/m to form a strong bond. Adhesives bead up, slide off, or peel away cleanly because of this gap.
The Role of Surface Energy in Adhesive Bonding
The degree to which an adhesive dampens the surface has a significant impact on adhesion. A bond may form if a liquid adhesive spreads readily and creates close molecular contact. Adhesives are unable to wet the substrate when surface energy is low, as it is with PTFE. Instead, they create thin films or droplets with weak van der Waals interactions to reduce contact. This is where Teflon coatings for SMC battery cover molds come into play, offering a nonstick surface that minimizes adhesion issues and promotes consistent mold release during production.

Teflon is strategically used as a release surface in manufacturing because, in normal circumstances, adhesives just do not stick, as this data demonstrates.
Common Adhesive Failure Mechanisms on Teflon
Several predictable kinds of failures arise when adhesives come into contact with PTFE:
Failure of Interfacial Adhesion
Peeling occurs immediately or over time as a result of the adhesive’s failure to achieve wetting or chemical interaction.
Often found in hot melt and cyanoacrylate (super glue) systems.
Cohesive Failure in Adhesive Layer
The bond may appear to hold at first for some pressure-sensitive adhesives, but it fails within the adhesive layer because there is inadequate anchoring.
Delayed Peeling and Edge Lift
Because of the ultra-slick PTFE surface and stress relaxation, labels or films may seem to stick under pressure but eventually peel off.
Thermal or Chemical Release
Teflon is helpful in high-temperature and chemical processing settings because exposure to solvents or elevated temperatures speeds up failure.
The effectiveness of PTFE-coated components for anti-fouling and release applications in production can be explained with these predictable failure mechanisms.
Industrial Applications: Why Manufacturers Use Teflon
Manufacturers also rely on nonstick coatings for tooling and fixturing to prevent material buildup, simplify cleanup, and maintain precision across high-volume production environments. These coatings produce a low-friction, smooth surface that keeps composite materials, adhesives, and resins from adhering to tools or molds. Components release cleanly as a result, negating the need for harsh cleaning agents or mechanical scraping, which over time could harm equipment.
These coatings aid in preserving consistency across production cycles in sectors like electronics, automotive, and aerospace where surface integrity and dimensional accuracy are crucial. They are a wise investment for any operation that prioritizes throughput and dependability because they also help to prolong tool life and reduce interruptions.
1. Food and Beverage Production
To stop sticky materials like dough, caramel, or sauces from building up, PTFE coatings are put on mixing vessels, baking molds, hoppers, and conveyors. This prolongs equipment life, reduces cleaning downtime, and avoids product contamination.
2. Chemical and Pharmaceutical Manufacturing
Teflon can withstand strong acids, solvents, and bases without degrading because of its chemical inertness. Surfaces remain clean and cross-contamination is avoided because adhesives and process residues do not stick.
3. Packaging Lines and Labeling Equipment
Non-stick chutes, plates, and rollers stop labels and films from collecting adhesive, which can lead to misalignments and jams. This lowers maintenance interventions and increases uptime.
4. Medical Device Production
Teflon offers non-stick, non-reactive surfaces that lower the risk of contamination in sterile settings. PTFE is frequently found in syringe barrels, catheter coatings, and transfer trays.
5. Composite Manufacturing and Molding
Teflon-coated tooling is used in the wind energy, automotive, and aerospace industries to avoid resin bonding during composite layups and curing, resulting in clean part release and less mold preparation.

When Bonding to Teflon Is Necessary
Although Teflon’s non-stick properties make it ideal for many applications, bonding is sometimes necessary. The conventional adhesive method won’t work in these situations. Surface alteration is necessary.
1. Chemical Etching
This is the most widely used industrial technique. An etchant based on sodium is used to partially remove the fluorine layer, resulting in a surface rich in reactive carbon. Epoxy, urethane, and acrylic adhesives can bond more successfully as a result of the significant increase in surface energy, which is frequently above 60 mN/m.
Pros: Strong, permanent bonds
Cons: Requires controlled handling, disposal of etchant, and proper surface prep
2. Plasma or Corona Treatment
These techniques modify the surface energy of PTFE without the use of harsh chemicals by using ionized gas. Although plasma treatment can increase adhesion, chemical etching for structural bonds might be more effective.
Pros: Environmentally cleaner
Cons: Equipment cost, bond strength is typically lower
3. Primers and Tie Layers
Certain specialty primers serve as a layer between adhesives and Teflon. For low-load applications, they provide moderate adhesion.
Pros: Simple process
Cons: Not suitable for high-performance bonding
Engineering Considerations for Teflon Use
Engineers need to think about more than just adhesive resistance when incorporating Teflon coatings into manufacturing systems.
Thickness and Application Method
Coatings can be applied through spray, electrostatic deposition, or as bonded liners.
Typical coating thickness: 0.002 to 0.010 inches, depending on application.
Thermal Performance
PTFE remains stable up to 260°C (500°F).
Excessive heat can cause degradation or off-gassing.
Abrasion and Wear
Even though PTFE is chemically stable, mechanical stress can cause it to deteriorate over time.
Wear resistance can be increased by reinforced coatings or blends (PTFE with PFA or fillers, for example).
Coefficient of Friction
0.05 – 0.10, one of the lowest of any solid, which helps with its self-lubricating and release characteristics.
Regulatory Considerations
FDA compliance for food-contact surfaces.
Cleanroom compatibility for semiconductor and medical applications.
Release Properties vs. Adhesion Resistance
It’s critical to know the difference between adhesion resistance and release properties.
Adhesion resistance: Adhesives don’t bond in the first place.
Release property: Material allows easy removal after temporary contact.
Teflon offers both. This dual characteristic is essential for processes involving curing resins or pressure-sensitive adhesives, mold release applications, and non-stick transfer surfaces.
Real-World Case Study: Labeling Equipment Downtime Reduction
Label misfeeds and adhesive buildup on rollers caused frequent downtime at a packaging facility that applied adhesive-backed labels to plastic containers.
Problem: Steel rollers developed adhesive residue that needed to be cleaned every day.
Solution: Steel rollers developed adhesive residue that needed to be cleaned every day.
Result: 95% less adhesive buildup was present.
The frequency of cleaning decreased from daily to every two weeks.
Because there were fewer stoppages, line speed rose by 8%.
In less than three months, the ROI on the coating cost was recovered.
This example shows how operational efficiency can be directly impacted by an understanding of adhesive behavior on Teflon surfaces.
Beyond Teflon: Alternative Non-Stick Materials
Although PTFE is the most well-known non-stick material and other fluoropolymers can also withstand adhesives:
Material
Key Features
Comparison to PTFE
FEP (Fluorinated Ethylene Propylene)
Melt-processable, transparent, and excellent chemical resistance
Easier to fabricate but slightly less temperature-resistant
PFA (Perfluoroalkoxy)
High purity, excellent chemical resistance
Better processability than PTFE
ETFE (Ethylene Tetrafluoroethylene)
High mechanical strength
Higher impact resistance but less non-stick
Silicone Rubber
High flexibility, low surface energy
Not as chemically inert as PTFE, but good release properties
These materials are frequently chosen according to fabrication requirements, cost, mechanical wear, and temperature requirements.
Testing and Quality Control
It is important to confirm Teflon coating performance in sensitive manufacturing environments:
Contact Angle Measurement: Verifies the integrity of the coating and surface energy.
Adhesion Peel Testing: Evaluates release performance against production adhesives.
Thickness Measurement: Provides wear tracking and consistent application.
Microscopy: Detects coating defects or damage.
Regular testing and inspection preserve consistent line performance and increase the service life of PTFE-coated components.
Limitations and Considerations
Even though Teflon has many advantages, it isn’t always the best option. Manufacturers need to take into consideration:
Mechanical Durability: Vulnerable to wear and scratches in abrasive conditions.
Thermal Cycling: Bond strength to the substrate may be impacted by repeated heating and cooling.
Cost: PTFE coatings are more expensive than many standard industrial finishes.
Repairability: Once damaged, Teflon coatings often need professional reapplication rather than spot repair.
Manufacturers can strategically use PTFE where its advantages are greatest by being aware of these tradeoffs.
Integrating Teflon into Production Design
For process engineers, the key to leveraging Teflon is strategic placement:
On surfaces where accumulation results in line slowdowns, apply PTFE coatings or liners.
Add non-stick surfaces to stations for mold release, labeling, and product transfer.
Determine the type and thickness of the coating when designing the equipment, not after issues have arisen.
To increase service life, combine coatings with preventive maintenance plans.
When applied intentionally, Teflon can reduce cleaning labor, extend production runs, and improve overall process control.
A Non-Stick Powerhouse Across Industries
Does a Teflon coating, then, stand up to adhesives? It does, quite effectively. It is one of the best non-stick surfaces in contemporary manufacturing because of its fluorinated structure, extremely low surface energy, and chemical stability.
This resistance is valuable for the majority of production lines because it prevents adhesive buildup, reduces fouling, and increases uptime. Additionally, engineered surface modification techniques can enable bonding when necessary.
Teflon is used in a variety of industries, including food processing and aerospace, to deliver clean, dependable, and predictable performance where it counts most. PTFE is still one of the strongest and most adaptable materials available to engineers and manufacturers looking to streamline operations.Contact Sun Coating todayto discover how our advanced Teflon coating services can enhance your equipment’s performance and reliability.
Posted by Sun Coating on | Comments Off on Teflon Coatings in Food Processing & Packaging: Driving Cleanliness, Efficiency, and Reliability
Maintaining product quality while optimizing efficiency is a never-ending challenge in the rigorous industry of food processing and packaging. From large-scale packaging facilities to industrial bakeries and snack producers, manufacturers must strike a balance between operational costs, hygienic requirements, and production speed. Teflon coatings are one solution that has shown great value in the industry. These nonstick coatings offer a number of advantages to food-related operations, including waste reduction, hygienic environment maintenance, and increased production efficiency.
Teflon coatings are crucial for extending the life of food production and packaging equipment and decreasing downtime. On baking trays, hoppers, wrappers, baggers, transfer and press plates, sealing bars, cartoning, form-fill-seal, and more, these coatings create smooth, nonstick surfaces that resist the buildup of oils, dough, chocolate, and other sticky substances. By reducing the chance of cross-contamination and the need for frequent cleaning, this promotes compliance with strict food safety laws. Because the coatings are heat-resistant, they function well in dryers, ovens, and heat-sealing devices without degrading. Additionally, their resistance to abrasive materials reduces replacement costs and maintenance delays. For manufacturers who have to deal with rising labor and energy costs, these advantages translate into measurable savings.
Food processors and packaging companies can increase productivity, maintain consistent product quality, and create safer, cleaner environments for workers and customers by incorporating Teflon-coated components into their production lines. This article examines the uses of Teflon coatings in food processing and packaging, their remarkable efficacy, and their essential role in contemporary manufacturing. We’ll also examine how manufacturers can use these coatings for their own facilities and how they relate to other industrial applications.
Why Teflon Coatings Are Vital in Food Processing and Packaging Operations
The nonstick qualities of Teflon, also referred to as PTFE (polytetrafluoroethylene), are well known. Although cookware is the product that most consumers are familiar with, its advantages go well beyond the kitchen. Teflon coatings produce surfaces in industrial settings that are tough, durable, protective nonstick surfaces. This results in a more streamlined and effective process for food processors.
The main benefits consist of:
Decreased Waste: Teflon coatings reduce material loss during processing by keeping dough, batter, or other food products from adhering to machinery.
Improved Sanitation: Teflon’s non-porous surface facilitates cleaning and aids in the maintenance of stringent hygienic standards in establishments.
Increased Productivity: Because there is less need for manual scraping and cleaning, machines run with less downtime.
Durability and Longevity: Teflon-coated surfaces are resilient to repeated use, which prolongs the life of expensive processing machinery.
Teflon coatings’ adaptability to various machinery types is another important advantage. PTFE works well in both cold storage and high-heat applications. Establishments can continue to adhere to food safety standards without risking equipment damage. Teflon coatings are a sensible option for businesses that handle a variety of products, from frozen foods to baked goods, because of their versatility, which also lowers the possibility of cross-contamination.
These benefits make Teflon coatings essential in a sector where efficiency and cleanliness have a direct impact on profit margins.
Applications of Teflon Coatings in Food Processing & Packaging
Numerous pieces of equipment used in food processing and packaging contain Teflon coatings. Among the most popular uses are:
Baking Equipment: Teflon coatings help molds, trays, and ovens stay clean and cook food evenly.
Conveyor Systems: By reducing product accumulation, coated conveyor belts simplify packaging and lessen jams.
Blenders and mixers: Teflon-coated surfaces prevent batter and dough from sticking to bowls and blades.
Equipment for Cutting and Slicing: Nonstick coatings make it possible for knives and slicers to cut more quickly without sacrificing accuracy due to food residue.
Packaging Equipment: Coated surfaces on rollers and sealers keep them operating smoothly and keep food particles out of the packaging.
These applications all show how coatings maximize food quality and production efficiency.
Nonstick Coatings for Tooling and Fixturing
In addition to food-specific equipment, Teflon coatings also play an essential role in supporting tooling and fixturing across industries. In particular, nonstick coatings for tooling and fixturing are valuable for adhesive-related processes. During packaging, glues and adhesives often come into play, and uncoated surfaces can quickly become messy and inefficient. Applying Teflon creates a protective, nonstick barrier that reduces downtime, prevents buildup, and simplifies cleaning.
For food manufacturers, this means smoother packaging operations, faster changeovers, and better overall quality control. By minimizing adhesive-related complications, businesses can save time and reduce product defects, resulting in higher profitability and customer satisfaction.
The Role of Teflon in Reducing Waste
The food industry as a whole prioritizes waste reduction. Revenue is lost for each ounce of batter, dough, or chocolate that sticks to machinery rather than making it into the finished product. Teflon coatings directly address this problem by maintaining buildup-free, smooth production surfaces.
For instance, thin chocolate layers that build up over time are frequently left behind by uncoated molds used in the confectionery industry. Teflon-coated molds maximize yield and minimize scrap by allowing chocolate to release cleanly. In bakeries, operators can recover more product per batch because dough and batter come off trays and pans more readily. Less waste results in cheaper material costs and more completed goods that can be distributed, which has a substantial cumulative effect.
Hygiene and Sanitation Benefits
In facilities that process and package food, food safety cannot be compromised. Recalls, harm to a brand, and fines from the government can result from contamination risks. Teflon coatings reduce these risks by creating surfaces that are easy to clean and don’t stick.
Over time, traditional metal equipment may get tiny scratches and pores that are home to bacteria and food residue. In contrast, the smoother surface of Teflon-coated equipment prevents the growth of microorganisms. Because of this, cleaning is completed more quickly and thoroughly, enabling facilities to continue adhering to FDA and USDA regulations. Teflon coatings save labor costs related to sanitation procedures while simultaneously protecting public health by simplifying cleaning protocols.
Greater Efficiency in Operations
In food processing, efficiency is about more than just speed; it’s also about maximizing throughput and decreasing downtime. Teflon coatings directly contribute to the accomplishment of this objective. Production lines can run continuously for longer periods of time because the equipment requires less frequent cleaning and has fewer sticking problems.
This effectiveness results in:
Increased daily production
Decreased dependence on manual labor for cleaning and scraping
Over time, lower operating costs
These small adjustments can add up to a significant edge for companies competing in markets.
Specialized Applications: EV Battery Mold Coatings
Although Teflon coatings are still mostly used in food processing, other industries can benefit from their adaptability. One emerging use is in the electric vehicle sector, particularly indemolding SMC for EV battery covers. Here, Teflon coatings help to release sheet molding compounds (SMC), which are essential for producing battery covers that are both lightweight and long-lasting.
This crossover demonstrates how versatile Teflon technology is. It simplifies sophisticated manufacturing procedures in automotive applications, much like it keeps food from adhering to molds. For professionals in the food industry, this reaffirms Teflon’s dependability and longevity as a coating solution that has been tested in numerous high-performance industries.
Environmental and Cost Advantages
Teflon coatings offer cost and environmental advantages in addition to operational efficiency. By reducing the amount of food that is thrown away, reduced waste directly supports sustainability initiatives. Teflon coatings also prolong the life of processing equipment, lowering the need for replacements and repairs and resulting in lower capital costs.
Because coated surfaces require less scrubbing and fewer cleaning agents, the amount of water and chemicals used during cleaning is also reduced. In addition to lowering operating expenses, this supports environmentally friendly procedures that many food businesses are working to adopt.
Future Outlook for Teflon in Food Processing
Teflon coatings’ use in food processing and packaging is anticipated to increase as technology advances. New developments in coating applications could result in even more robust, specialized solutions for particular kinds of equipment and food items. Furthermore, coatings that reduce downtime and increase consistency will be more in demand as automation and high-speed production lines become more important.
The future of Teflon coatings will probably be shaped by the growing significance of sustainability, with research concentrating on lowering energy consumption and prolonging product life cycles. Teflon coating adoption will keep growing as more manufacturers become aware of these advantages.
The Lasting Value of Teflon in Food Processing
Teflon coatings are an essential part of contemporary food processing and packaging operations, and they are much more than just a convenience. These coatings provide quantifiable benefits to the industry by decreasing waste, enhancing hygiene, increasing productivity, and promoting sustainability. The use of Teflon technology has revolutionized the production and distribution of food in everything from bakeries to packaging facilities.
Manufacturers can investigate customized coating solutions that meet their unique requirements in order to benefit from these advantages.

Posted by Sun Coating on | Comments Off on Is Ceramic Coating Safer Than Teflon?
If you’ve ever browsed cookware aisles or researched industrial coating options, you’ve likely encountered both Teflon (PTFE) and ceramic coatings. For those in the food manufacturing and processing industries, the choice goes beyond aesthetics or cost—it touches on safety, durability, and efficiency. That’s why many professionals ask, is ceramic coating safer than Teflon?
At Sun Coating Company, we specialize in advanced non-stick coating services, providing reliable, high-performance solutions for diverse applications, including food processing coatings. Our expertise in coating technologies helps clients in critical sectors make informed, safety-conscious decisions.
What is Teflon and Why Has It Been Controversial?
Teflon is the trade name applied to the synthetic polymer PTFE (Polytetrafluoroethylene), which has been famous for several decades due to its extraordinary non-stick and chemical resistance properties. Since its discovery in the 1930s, PTFE has been widely used as an ingredient in cookware, machinery, and industrial equipment. Its popularity, however, has been tarnished by a history that includes the use of a chemical compound called PFOA (Perfluorooctanoic Acid) in the production process.
Although PFOA has been phased out of Teflon production since 2015, there are still concerns about high-temperature degradation of PTFE. Heating Teflon pans to over 500°F can cause the material to release fumes, which can be the cause of flu-like symptoms in humans and are highly toxic to birds. Although PTFE is deemed safe under normal use by regulatory agencies like the FDA, its safety is greatly dependent on how it’s stored and handled.
For use in industry, e.g., food processing, such factors gain even greater importance. Failure of coatings or thermal degradation of equipment for contact with food can shut down production and create hazards. For this reason, it’s critical to understand the composition and thermal stability of each type of coating when making coating solutions.
How Ceramic Coatings Differ—and Their Safety Profile
Ceramic finishes have also become popular, especially in the form of a PTFE-free offering. Ceramics are generally made by the application of sol-gel fabrication of inorganic minerals, primarily silica, which can be obtained from sand. They result in a smooth, hard, glossy non-stick finish with some advantage from heat resistance and subjective protection of health.
Ceramic coatings are both PTFE-free and PFOA-free, meaning they also appeal to consumers who want to entirely rid their equipment of fluorochemicals. Ceramic coatings tend to be more heat-resistant without degrading or fuming, which has particular appeal to manufacturers and consumers interested in safety in high-heat environments. This is particularly relevant to food processing, where equipment must be resistant to the frequent exposure to high heat without compromising chemical contamination.
However, ceramic coatings do wear more quickly than quality PTFE substitutes. Over time, ceramic’s non-stick properties will fade, especially if used hard or exposed to metal cutlery. Though not typically immediately detrimental to health, this wear does lead to less efficiency, increased sticking, and a need for earlier replacement.
Evaluating Durability and Environmental Impact
In terms of longevity, PTFE coatings—particularly those applied using professional-grade techniques—last longer than their ceramic counterparts. At Sun Coating Company, our coating processes are engineered to maximize coating life, even in severe environments. This makes PTFE a perfect choice for long-term performance in industrial and commercial applications.
Environmental impact is another consideration that affects coating choices today. Ceramic coating is commonly touted as the greener choice because it has a less complex mineral-based composition and requires less energy in production. However, although PTFE production is better now, its environmental impact is still a worry for certain industries.
Nevertheless, ceramic and Teflon coatings made and installed according to strict guidelines are safe according to the FDA and other international authorities on health as long as they are used correctly. The trick lies in getting high-quality coatings from reliable suppliers and installing them with professional flair—something Sun Coating has been thoroughly happy to offer for more than 50 years.
Which is Safer: Ceramic or Teflon?
So, is ceramic coating safer than Teflon? The answer depends on how you define safety. If avoiding all fluorochemicals is your top priority, ceramic offers a clear path. It contains no PTFE or PFOA and boasts impressive heat resistance. However, it may not offer the same longevity or consistent non-stick performance over time, particularly in high-demand applications.
Modern Teflon coatings, especially when applied by experienced providers like Sun Coating Company, are engineered for safe, stable use. When used properly—avoiding excessive heat and handling with care—PTFE remains a highly reliable and safe option for industrial settings where consistency and long-term performance matter. This durability can outweigh the theoretical risks associated with overheating.
Making the Right Choice for Your Application
When choosing between ceramic and Teflon, it’s essential to assess your specific needs—whether it’s for cookware, manufacturing equipment, or high-volume food processing coatings. Ceramic may be the right choice if maximum chemical safety and high-heat tolerance are essential. Teflon may be ideal if long-term durability and proven non-stick performance are critical.
At Sun Coating Company, we work with clients across food processing, packaging, and industrial manufacturing to provide tailored coating services that meet strict safety, performance, and compliance standards.

Posted by Sun Coating on | Comments Off on What Industries Benefit the Most from High-Performance Coatings?
High-performance coatings are used in a variety of industrial settings for different types of equipment and their requirements. They’re used in mining operations, food processing, and automotive to name a few. For many industries, industrial coatings make their operations much more efficient, prevent contamination, and extend the working life of equipment.
The purpose of an industrial coating is to protect both the surface of the vessel and the material that it contains for the short and long term. Here’s a look at some of the industries that benefit from the use of high-performance coatings.
Molding and Stamping Industries
Stamping and molding dies are used to use high heat and pressure to press or mold steel or plastic into a final form. The dies require a coating to protect it from the heat of the press while preventing the part from sticking. The coating also has to be thin enough to maintain the tolerances of the die. A high-performance coating like Sunoloy® does all of this and more, resulting in fewer bad molds and stampings.
Automotive Manufacturing
Vehicles are made up of many moving parts, with these parts subject to wear and friction due to their rotational nature. Both auto and automotive parts manufacturers benefit from using high-performance coatings such as Excalibur Coating. A fluoropolymer coating reinforces the metal it’s applied to and reduces friction for the smoothest possible operation and longevity of the part.
Mining
The mining industry is hard on its equipment due to the abrasive nature of moving large quantities of material in various formats. Excavator buckets, conveyor belts, and pipes are just some of the types of mining equipment that benefit from industrial coatings. Durable coatings with high abrasion and heat tolerance are capable of protecting mining equipment from sustaining damage and can also resist build-up for longer. These properties also prevent corrosion and rust from eating away at the equipment.
Medical
The medical industry as a whole benefits from the use of coatings that are designed for a specific purpose. Pharmaceutical research involves the use of chemicals that can damage equipment, and prosthetics rely on lubrication to aid in the movement of artificial joints. Coatings in the form of dry lubricant films and non-stick finishes aid in the operation of these items and more. Furthermore, coatings can be applied to medical and surgical tools for better performance.
Food Processing
The food processing industry uses industrial coatings for their cooking vessels and food processing equipment for ease of cleaning and optimal performance. When it comes to getting the most out of a coating, Chemours Teflon® finishes delivers on its ability to protect a vessel, withstand high heat, and won’t leech chemicals into the food. These properties reduce downtime, minimize the risk of contamination, and extend the lifespan of the unit.
Packaging
Packaging manufacturers rely on equipment that uses heat to perform a process. That is, a heat sealer uses a blade to sear and cut plastic, bagging machines heat seal bags, and blister packing has to use heat to seal the foil to the plastic. The plastics and foils used in these processes eventually leave behind residue that needs regular removal. An industrial coating, such as a Teflon® PFA, protects the heated surface and makes it easier to clean.

Posted by Sun Coating on | Comments Off on Can Industrial Coatings Be Reapplied?
The short answer to the question is yes; industrial coatings can be reapplied whenever necessary. It’s possible to reapply most types of industrial coatings as they’re designed for reapplication when the original one wears off. Reapplication can also be done partly or whole, depending on the level of degradation of the original coating. The following is a look at what’s involved in reapplying an industrial coating to your equipment.
Why Industrial Coatings Degrade
Degradation happens for various reasons, with the major ones being wear and tear, weather, and impacts on the equipment. Industrial environments tend to be harsh ones, something that causes the compounds in the coating to break down over time. This happens to every coating, with the difference coming in the form of quality. For example, Teflon FED coatings can last for years due to their resistant properties and are easily reapplied when the current coat has worn away.
Should You Stick With the Same Coating?
In most cases, yes, you should have the original coating material reapplied. For example, a piece of equipment had one of the Chemours Teflon coatings applied for waterproofing. The equipment was designed to be used with a specific coating in order to be as effective as possible and also aid in longevity. During the design process, the lifespan of the coating was taken into consideration, and an instruction for reapplication was included in the paperwork for the equipment.
What this means is that reapplying the same coating is in alignment with what the designer intended when they created and tested the unit. Using the same coating is the best course of action as it restores the unit back to its original state and level of effectiveness.
Sometimes it happens that a coating gets discontinued, which means you have to switch to a different coating material. Look for a coating material that’s similar in chemistry and properties, or check with an industrial coating supplier to learn more about alternatives. It’s also a good idea to contact the manufacturer for guidance in the event a warranty is still in effect on the unit.
The Benefits of Reapplying Industrial Coatings
Industrial equipment is designed to be durable and lasting under heavy use and weather conditions. Industrial coatings play a role in the durability factor, but they don’t always last as long as the equipment. However, if you don’t keep up with reapplication, you’re exposing the unit to atmospheric conditions that can cause deterioration.
If you’re not sure about reapplying an industrial coating to your equipment, contact the equipment manufacturer or an authorized repair service to learn more. Most of the time, a piece of equipment can get re-coated, but knowing is better than assuming.
Making Your Reapplication Last Longer
Coatings have a tendency to deteriorate in patches, but they can also disappear in their entirety. When you find that the coating is looking patchy, you have the option to take off the remainder for a full re-coating or fill in the patches.
Filling in the patches makes sense when they’re limited to small areas and most of the original coat is still intact. The patching makes the coating whole again and is effective at protecting the surface. In the event the coating has large patches, it’s best to strip the surface clean and start fresh with a new coating.

Posted by Sun Coating on | Comments Off on How Coatings Improve Chemical Resistance in Harsh Environments
All manufacturing processes are going to rely on metal equipment for production. However, this presents a problem. Metal is vulnerable to a wide array of external threats, both in regard to the manufacturing facilities, if the metal in question is used in the equipment needed for production, as well as in regard to the equipment that metal parts are used for once they leave the facility and are used in business and consumer products. This is where protective coatings come in. Protective coatings are a must for any business involved in industrial production. But how do these protective coatings work? What do you need to consider when seeking protective industrial coatings for your own business purposes? Here’s a closer look at how coatings improve chemical resistance in harsh environments. Once you’re ready to find protective industrial coatings for your business, you can request a quote here from Sun Coating Company.
What Are Industrial Coatings?
Industrial coatings refer to any coating that is applied to a substrate. While there is a myriad of industrial coatings to choose from, such as anti stick coating and powder coatings, the end goal is the same: to apply a protective coating that effectively binds to the underlying substrate so as to protect it against the various stressors and hazards that it will encounter during use. What’s important to note about industrial coatings is that not all coatings are going to be suitable for all environments. Some coatings may be excellent for reducing abrasion but may not be able to hold up so well against chemicals they come in contact with. Others may be chemical resistant but may not hold up against higher temperatures, which can present problems during the manufacturing process and beyond. This presents an important question: which industrial coatings offer chemical resistance, and how?
Examples of Industrial Coatings and How They Improve Chemical Resistance
Not all coatings are chemically resistant, and this is due to the makeup of the product being used. For example, a basic acrylic coating may serve to protect a substrate from abrasion, but chemicals will eat right through it as it’s not able to defend itself against the harsher compounds it comes in contact with. Certain industrial coatings are far more effective at being chemically resistant. How? The industrial coatings that will defy chemicals feature tight molecular bonds and non-porous surfaces that prevent chemicals from working their way into and through the coating. The denser and stronger the coating, the more likely it is to protect substrates against chemicals.
But which protective coatings are chemically resistant? Some of the top coatings worth considering if you’re seeking to defend substrates from chemicals include:
Fluoropolymer-based coatings, such as Whitford nonstick solutions, are capable of shielding substrates against hydrochloric, nitric, phosphoric, and sulfuric acid, just to name a few. As with many other coatings, you can also expect abrasion resistance and high-temperature resistance.
Polyurethane-based coatings are adept at defending substrates against a wide range of caustic chemicals as well as other hazards like hydraulic oil, acids, and solvents.
Epoxy-based coatings are a popular protective coating option. It protects against an array of chemicals, including everything from fatty acids to salt solutions and chemical cleaning detergents.
When you’re looking for chemically resistant industrial protective coatings, you should also consider custom options. Custom industrial coatings will help you get the specific chemical resistance you demand and specific benefits you may not get with broadly tailored products.

Posted by Sun Coating on | Comments Off on The Impact of Temperature on Coating Performance
Coating, much like most things related to industrial processes, is a science. Coating can be done wrong, and there are many factors that can lead to poor coating performance immediately after a coating has been applied. One of the major factors that can play a role in coating performance and efficacy is temperature. The coating needs to be done at just the right temperature, which will vary depending on the type of coating being applied. More than that, other temperature-related factors like ambient temperature and substrate temperature can play a role. What happens when you try to apply a coating when the temperature is too low or too high? Let’s see how temperature can impact coating performance and why you should get substrate professionally coated by Sun Coating Company.
How Low Temperatures Impact Coating
Let’s imagine that you’re working with Teflon FEP coatings, and you’re starting the coating process long after the coating has had a chance to cool down. What might you expect when this happens? Cool temperatures can have a massive impact on the coating process. When temperatures are too low, coatings will often have a hard time binding to the substrate, will be slow to cure in comparison to how fast they’d cure if they were put on at the right temperature, and would likely result in a poor finish. Of course, surface-level issues like discoloration and an uneven surface are the least of your concerns. The coating applied at a low temperature will be entirely ineffective at its job, potentially coming off easily or breaking as well as introducing all of the various elements you’re trying to keep out onto the substrate. If you’re attempting a coating or you’re getting it professionally done, always make sure that it’s being done at the correct temperatures.
How High Temperatures Impact Coating
Attempting coating when the coating is too hot is unlikely to lead to as severe issues as the above, correct? Not exactly. While the issues might not look as dramatic, trying to apply corrosion resistance coatings and other coatings before they should be applied can lead to many issues as well. The primary problem with coating at a high temperature is rapid drying. Rapid drying results in uneven application. While not sagging, you’re still not getting the full and secure coating that your materials need to remain protected against industrial threats. More than that, coating at a high temperature will begin to show signs of coating issues, including but not limited to cracking, blistering, and skinning. Things you might not see until much later in a coated substrate’s life become evident immediately when you begin coating far too quickly.
Receive Proper Coating With Sun Coating Company
Successful coating depends on making sure the coating used is being applied at the right temperature. Too low of a temperature gives you a coating that is not bonded correctly and has a host of other issues that make it useless immediately after it has finally hardened. Too high of a temp completely ruins the coating, even if it looks like it’s on there a bit tighter, requiring immediate replacement as well.

Posted by Sun Coating on | Comments Off on Why Is My Industrial Coating Failing?
As a leading industrial coatings company, our team at Sun Coating Company understands how frustrating it can be when coatings fail prematurely. Our goal is always to provide coatings that stand the test of time in even the harshest industrial environments. However, despite any company’s best efforts, coatings can still fail sometimes. Here are some of the most common reasons coatings fail and provide tips to help prevent failures.
Surface Preparation Issues
One of the most common reasons industrial coatings fail is inadequate surface preparation. Coatings require a clean, contaminant-free surface to properly adhere. Any dirt, oil, grease, rust, or other contaminants can cause coatings to lose adhesion. Even unseen contaminants like vapor residues can lead to coating failure down the road.
Thoroughly clean and degrease surfaces before coating application. On metals, remove any rust and create the proper surface profile for mechanical bonding. Inadequate surface prep accounts for over 60% of industrial coating failures. Don’t cut corners here.
Incompatible Materials
Coatings are formulated for specific materials like steel, aluminum, and plastic. When a coating isn’t compatible with the substrate, the result is usually premature failure. Using a coating meant for steel on aluminum will likely lead to delamination or blistering.
Always verify coating compatibility and use coatings formulated for your specific substrate. At Sun Coating Company, we can recommend compatible coatings for virtually any substrate. Our coatings, like polyurethane foam mold coatings, are engineered for common industrial materials.
Incorrect Film Thickness
Applying coatings at the wrong film thickness is a very common mistake. Coatings applied too thin won’t provide adequate protection and durability. Overly thick coatings will experience sagging, cracking, or imprinting.
Follow the product data sheet for proper film thickness and confirm thickness with wet film gauges during application. Too thick or thin by more than 10% often leads to failure. Proper film thickness ensures optimal performance.
Curing Issues
Coatings require time and the proper conditions to fully cure. When coatings don’t fully cure, performance will be severely impacted. Coatings may never reach full hardness or chemical resistance.
Allow adequate time for coatings to cure based on product data sheets. Ensure the required temperature and humidity levels for curing are met. Forced curing can be used to accelerate cure times when necessary. Uncured or partially cured coatings will almost always lead to premature failure.
Exposure Before Curing
Exposing coatings to chemicals, abrasion, or other factors before fully curing is another common mistake. Coatings in the curing process are vulnerable. Any exposure can permanently damage the coating, quickly leading to failure once put into service.
Isolate freshly applied coatings from all chemicals, abrasion, fluids, and other factors until completely cured. Avoid touching, walking o,n or otherwise disturbing curing coatings. Patience during the curing process will pay off.
Off-Ratio Mixing
Two-component coatings require mixing resin and catalyst at the proper ratio. When off-ratio mixing occurs, coatings will not cure correctly. They’ll remain tacky and soft, rapidly failing once put into service.
Carefully follow mix ratios and measure components precisely. Calibrate spray equipment regularly to ensure proper metering. Confirm ratios with periodic scrape tests. Off-ratio coatings must be fully removed and reapplied correctly.
Poor Surface Profile
An adequate surface profile provides the mechanical bonding that coatings require for abrasion and impact resistance. Surfaces that are too smooth prevent mechanical bonding, limiting coating adhesion. This is especially important for a dry film lubricant coating.
Achieve the recommended anchor profile for each coating, typically 2+ mils. Blasting, power tools, and chemical etching all create a proper profile. Slick surfaces like stainless steel may require abrasive blasting. The profile should appear uniform and jagged under inspection.
