Fluoropolymer coating compositions containing adhesive polymers and substrate coating process

摘要

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