In a first aspect, a liquid fluoropolymer coating composition includes a fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride, a mixed catalyst, solvent, a compatible cross-linkable adhesive polymer and a cross-linking agent. The mixed catalyst includes a main catalyst and a co-catalyst. The main catalyst includes an organotin compound. In a second aspect, a fluoropolymer coated film includes a polymeric substrate film and a fluoropolymer coating on the polymeric substrate film. The fluoropolymer coating includes a fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride, a compatible cross-linked adhesive polymer, and a mixed catalyst. The mixed catalyst includes a main catalyst and a co-catalyst. The main catalyst includes an organotin compound. In a third aspect, a process for forming a fluoropolymer coated film includes coating a polymeric substrate film with a liquid fluoropolymer coating.
