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

   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 select.  PTFE 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

   August 17, 2020 2:20 pm 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.
