Abstract

See full text

In a first aspect, a transparent fluoropolymer coated film includes a polymeric substrate film and a fluoropolymer coating on the polymeric substrate film. The fluoropolymer coating includes fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride blended with a compatible adhesive polymer and a light stabilizer. The transparent fluoropolymer coated film has a transmission of at least 75 percent in the visible range. In a second aspect, a building structure comprising a transparent fluoropolymer coated film. In a third 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 light stabilizer including a combination of a UV absorber and a hindered amine light stabilizer, solvent, a compatible cross-linkable adhesive polymer and a cross-linking agent.
