Abstract:
1. A process for making a fluoropolymer coated polymeric substrate comprising: applying a primer layer to a surface of a polymeric substrate; applying a liquid fluoropolymer coating composition to said surface of said polymeric substrate, said fluoropolymer coating composition comprising fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride polymer; solvent comprising propylene carbonate; and compatible adhesive polymer comprising functional groups selected from carboxylic acid, sulfonic acid, aziridine, amine, isocyanate, melamine, epoxy, hydroxy, anhydride and mixtures thereof; said primer layer comprising amine functional groups that interact with said compatible adhesive polymer to promote bonding of said fluoropolymer coating to said substrate; and removing the solvent from said coating composition applied to said substrate to form a fluoropolymer coating on said substrate.
