A new generation of polyvinyl fluoride film has been specifically developed for use as a primer surface for automotive components which cannot otherwise be decorated with regular OEM paints, or where improved adhesion between the paint and the part is desired. Special film surface modifications provide for excellent adhesion between the film and a broad range of OEM and refinish paints. Lab and proving ground testing demonstrate solid performance throughout the exposure cycles required by FBMS 1–38. Current applications include vinyl and aluminum parts. The polyvinyl fluoride film is applied by lamination to extruded plastic or to coil stock using acrylic and acrylic/epoxy adhesives with proven outdoor durability. For parts subject to aggressive gravel attack, or where bonding to plastic parts is desired simply by heat fusion, a laminate of polyvinyl fluoride with a thin plastic face sheet can be used. Paints are applied according to normal operating procedures. This includes baking temperatures up to 300°F subject to the dimensional stability of the part. The chemical resistance of polyvinyl fluoride allows the use of virtually any chemical or solvent without attack to the film.
