The Science Behind Fluoropolymer Coating

Fluoropolymer coating, which is also called release coating, is an extremely important product for manufacturers in myriad industries, including (but not limited to) the aerospace industry, the automotive industry, the medical industry, and even the cookware industry. 


Why is fluoropolymer coating so popular? Because of its many useful properties, of course! Fluoropolymer coating is extremely durable, highly corrosion resistant, and able to withstand extreme temperatures. However, the thing it is most known for is its nonstick and friction reduction properties. 


To understand how fluoropolymer coating works, we need to understand what it is. Let’s start with the basics— fluoropolymer coating is made of a specific type of polymer. A polymer is a chemical compound (which can be naturally occurring or synthetic) made up of long, repeating chains that are bonded together. Fluoropolymer specifically is made of chains of fluorocarbons, which are compounds made up entirely of fluorine and carbon. 


The fluorine in fluoropolymer coating is largely responsible for its most famous attributes, because it is electrically negative. The fluorine’s electrically negative charge makes it very difficult for the fluoropolymer to bond with other materials. In practice, this results in friction reduction and the nonstick properties release coating is most known for. 


Fluoropolymer coating’s other useful characteristics (like corrosion resistance, chemical resistance, and overall durability) are also directly related to the relative atomic structures of fluorine and carbon, and the specific way in which they bond when they form fluoropolymer. 


So, there you have it; fluoropolymer coating works because of the interaction between the elements it’s made of.
