TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The cross-linking, removing, and adhering steps are performed by heating. The heating step further comprises coalescing the fluoropolymer. The heating is a single heating. The heating step comprises heating to 150-250 degrees C. The step of cross-linking the compatible cross-linkable adhesive polymer comprises forming a polyurethane network. The adhering step comprises forming bonds between functional groups of the polymeric substrate film and the compatible cross-linkable adhesive polymer and/or the cross-linking agent. The process further comprises modifying the polymeric substrate film prior to coating to provide additional functional groups capable of forming bonds with the compatible cross-linkable adhesive polymer and/or the cross-linking agent. The modifying step comprises using a surface activation process. The coating step comprises coating both surfaces of the polymeric substrate film with the fluoropolymer coating. Preferred Components: The fluoropolymer is in the form of particles in a dispersion. The compatible crosslinkable adhesive polymer is: polyesters, polycarbonates, acrylics, polyethers, ethylene vinyl alcohol copolymers, amides, acrylamides and/or urethanes; or polyester polyols, polycarbonate polyols, acrylic polyols, polyether polyols and/or ethylene vinyl alcohol copolymers. The cross-linking agent comprises an isocyanate functional compound or a blocked isocyanate functional compound. The polymeric substrate film is: unprimed polymeric substrate film; or unmodified polymeric substrate film. EXAMPLE - Desmophen F-2060B (RTM: Polyester including ethylene glycol, 1,4-butane diol, trimethylolpropane and adipic acid) (660 wt equivalent) was combined with a 42% solids polyvinyl fluoride (PVF) dispersion in propylene carbonate (30 parts polyester per 100 parts PVF using 50% solids solutions of the polyesters in propylene carbonate), Desmodur N-3300 (RTM: Polyisocyanate cross-linking agent) (1 equivalent) relative to polyester hydroxy content and dibutyltin dilaurate (0.02 parts/100 parts PVF). The resulting mixture was shaken on a paint shaker for 15 minutes. The mixture was drawn down on an unmodified Melinex 442 (RTM: Polyester film) (3 mil) using a 12 mil draw down knife. A heavy bead of pure PVF dispersion was applied along one edge of the wet test film to produce an aid in initiating peeling after baking. The coated film was baked in a 220 degrees C oven for 5 minutes using frames to hold the film. After cooling, the pure PVF bead was used to initiate peeling, to give the multilayer film.
