Polyvinylidene fluoride (PVDF)

A highly nonreactive thermoplastic fluoropolymer. PVDF, known by the registered trade names of Kynar 500 and Hylar 5000, is used as the principal ingredient in high-quality paints and protective coatings for metals, including architectural sheet metal and metal roofing applications. PVDF coatings have good gloss and color retention and are reported to resist chalking, cracking and fading.
