It is a resin used in architectural coatings that has exceptional weathering characteristics. PVDF stands for polyvinylidene fluoride. It is also known as "Kynar", or more properly, ®Kynar 500. ®Kynar 500 is a registered trade mark of Arkema Inc. North America, Inc. To quote Arkema: "Kynar® polyvinylidene fluoride (PVDF) resin is one of the most stable and pure of all commercial resins. It resists strong acids, solvents, and reducing agents and is used in several industries, including electrical and electronic manufacturing, chemical processing, pulp and paper, and transportation." The word Kynar is being used in everyday conversation the way the trade name "Kleenex" is used with tissues. However, as long as Arkema continues to protect its right to the trade name "Kynar 500," the generic way to describe it is "polyvinylidene fluoride" or "PVDF." This is not exactly the same thing as "Fluorocarbon resin." PVDF is one of several Fluorocarbon resins. Another trade name used for PVDF is ®Hylar 5000. Hylar 5000 is a registered trade mark of Solvay Solexis. Newlar by Spraylac also has 100% PVDF compared to 70% by others.
