  1. Top 4 Tips for Choosing the Right Fluoropolymer for the Job

    Leave a Comment

    Sun Coating prides itself on maintaining the highest quality finished coatings in the coating services industry. When people are looking for a fluoropolymer to solve a problem, they often think of the Teflon™ brand first, but what should you consider when choosing the coating?

    The versatility of these coatings allows almost unlimited application to a wide variety of parts, sizes and configurations, always adding value far beyond the inherent nonstick qualities. But, did you know the Teflon coating line actually consists of over 150 different systems and four fluoropolymer chemistries?

    In order to ensure that you pick the best fluoropolymer coating for your application, be sure to consider the following.

    • Substrate

    Teflon coatings are compatible with most ferrous and non-ferrous metals. Still, because these products are head-applied, properties of the metal allow must be considered, including its oxidation stability to ensure adhesion of the coating as well as preserving part geometric and dimensional integrity. Coatings add thickness, so it will be equally important to make allowances based on the product of choice.

    • Performance Requirements

    The Teflon coating line can provide a variety of benefits depending on chemistry and coating system that you selectPTFE coatings provide the lowest coefficient of friction, while FEP systems can offer superior release (nonstick). PFA coatings can enhance durability and resistance to corrosion, and ETFE coatings will offer increased resistance to abrasion and chemical resistance.

    • Project Budget and Value

    For finished, production-scale items, when cost-drivers are integral with overall value, Teflon S can be an effective solution.

    • End Use Environment

    In addition to understanding the mechanics of use when selecting a coating, it is equally important to identify the end-use environment and the type of exposure to ensure performance objectives are met.

    Now that you know the things to consider for selection, Teflon and Sun Coating Company have the resources to help you solve all your coating problems.

  2. How Nonstick Coatings Are Replacing Release Agents

    Leave a Comment

    To compete in a global economy, most areas of manufacture and industrial processing must find ways to make their products better, faster, and safer, while lowering costs of production. Many recognize that overcoming “sticking” is a way to achieve their bottom-line. But they resort to release agents which, at best, create a temporary “fix”. Quickly they discover release agents add considerable expense, labor, maintenance, and downtime. When not applied correctly, cleanup can be difficult, contribute to issues affecting quality and safety.

    From automotive to aerospace, food processing to consumer packaging, adhesives, inks, and printing, plastics, rubber, and molding-nonstick coating brands such as Teflon™, Xylan®, and Sunoloy® eliminate release agents, while delivering long-lasting performance and a multitude of benefits.

    Choosing the right PTFE, PFA, or FEP fluoropolymer-based coating for the job requires considerable knowledge, expertise, and the ability to fully understand the customer’s needs. This is the role of the coating service provider. Sun Coating Company, with its nearly sixty years in the industry, readily distinguishes itself by building lasting relationships with our customers, helping them achieve their goals.

    Knowing what to look for in the end-use environment, the mechanics of use, is paramount to determining the ideal mold release coating, for example. Factors such as temperature, nature of the “sticky” adherent, allowance for coating thickness, type of substrate, sources for abrasion, and product appearance are just some of the considerations in coating selection.

    What we have learned at Sun Coating is that surface attributes within a coating can be altered in measurable ways. The result is proprietary enhancements in surface and functionality not otherwise realized in areas such as thermoforming, two-shot or rotational molding, hot plate welding, laminating, heat sealing, and more.

    Recently, a major cheese processing facility reached out to us. Their cutting blades, coated by a competitor, were not working as promised. After our visit, Sun Coating learned that, initially, the release worked, but performance dropped off rapidly on their high-speed line. Using a black light, Sun Coating discovered moisture in the cheese was preventing clean, precise cuts and was able to remedy the situation, provide the right properties and coating for the job.

  3. What Being a Chemours® LIA Means for Sun Coating—and You

    Leave a Comment

    Sun Coating prides itself in maintaining the highest quality finished coatings in the coating services industry. Being a Chemours® Teflon™ Licensed Industrial Applicator (LIA) has been a significant component of Sun Coating’s success, reputation, credibility, and consistency over the years. And it also helps that when people are looking for a fluoropolymer to solve a problem, they often think of the Teflon™ brand first.

    Sun Coating has been LIA-certified continuously for over 30 years. The LIA program requires a coater to have extensive experience in applying Chemours Teflon™ coatings, as well as tight quality controls and proven consistency in finished coatings. Chemours began the program to stress that Teflon™ coatings require specific application procedures and expertise to engineer the appropriate application system so that every coating will perform optimally.

    Sun Coating President Mark Tate explains the importance of being an LIA. “It gives credibility to our company right away when speaking with potential customers,” says Mark. “And it says my organization is worthy, that Chemours believes in us.”

    The long-standing LIA program is an elite group of coating companies that have extensive knowledge of Teflon™ industrial coatings and experience in recommending and applying fluoropolymers in a variety of applications. In order to be selected as an LIA, these companies have met a list of criteria and qualifications as well as quality of workmanship. There are currently only 28 coating services companies in the U.S. that are LIA-certified.

    Sun Coating Company is also certified to IATF 16949:2016 and ISO-9001:2015 quality standards. Both of these standards recognize the highest performance within Quality Management Systems. Mark Tate believes Sun Coating is the only coating services provider with the IATF recognition.

    “We coat every part under the same quality material processes and quality control manuals,” Mark continues. “And we’re diversified. We can coat very small and very large parts as well as part volumes in the millions.”

    Sun Coating has grown steadily since its founding in 1962, but peak times of business growth have coincided with automotive industry growth. Sun Coating supplies extensive coating services for Tier 1, Tier 2, and OEM suppliers under the tightest quality scrutiny.

    Today, Sun Coating looks to 3D printing as a growth category. The durability, release, and corrosion-resistant properties of Teflon™ coatings make them ideal for metal parts in 3D printing. Another reason for this growth is the competition among new 3D printing technologies, as there are many different methods vying for market share.
