The present invention discloses a method for forming a multilayer film comprising coating a polymeric substrate film with a liquid fluoropolymer coating. The liquid fluoropolymer coating comprises a fluoropolymer, a solvent, a compatible cross-linkable binder polymer, and a cross-linking agent. The method also includes crosslinking a compatible crosslinkable binder polymer to form a crosslinked polymer network in the fluoropolymer coating, removing solvent from the fluoropolymer coating, and allowing the The fluoropolymer coating is bonded to the polymeric base film. Liquid fluoropolymer coating composition comprising a fluoropolymer selected from the group consisting of homopolymers and copolymers of vinyl fluoride, a solvent, a compatible crosslinkable binder polymer, and a crosslinking agent And homopolymers and copolymers of vinylidene fluoride. A fluoropolymer coated film includes a polymeric base film and a fluoropolymer coating on the polymeric base film. The fluoropolymer coating comprises a fluoropolymer and a compatible cross-linked binder polymer. |
