The second adhesive layer comprises a heat stable, radiation curable adhesive composition which loses its adhesive characteristics upon exposure to radiation.

Abstract: A flexible, weatherable, decorative sheet material useful as a paint film or decal comprising a pigmented fluoropolymer base coat layer overlying a substantially transparent fluoropolymer clear coat layer wherein the fluoropolymer composition of the base coat layer has a greater elongation than the fluoropolymer composition of the clear coat layer. The base coat and clear coat layer each comprise an alloy of a fluoropolymer composition and an acrylic polymer composition. The base coat layer comprises a fluoropolymer copolymer composition and the clear coat layer comprises of a fluoropolymer homopolymer composition. The fluoropolymer used in the base coat layer has a produced elongation at break of 300% or greater and the fluoropolymer composition used in the clear coat layer has a produced elongation at break of 50% to 250%. The clear coat and base coat layers are cast onto a polyester carrier sheet.

Abstract: A flexible composite surfacing film for providing a substrate with desired surface characteristics is disclosed. The film comprises a flexible temporary carrier film and a flexible transparent outer polymer clear coat layer releasably bonded to the temporary carrier film, the flexible outer polymer layer comprising an extruded thermoplastic polymer having a M.sub.w /M.sub.n ratio of 4 or lower. A pigmented base coat layer is adhered to said outer clear coat layer and is visible therethrough, and a thermoformable backing layer is adhered to the pigmented base coat layer. The film is produced by extruding a molten transparent thermoplastic polymer and applying the polymer to a flexible temporary carrier thereby forming a continuous thin transparent film.

Abstract: An apparatus for depositing a coating material, such as an organic monomer, in vapor form onto a substrate including a heated evaporation chamber having an inlet for introduction of the coating material into the chamber and a nozzle having an adjustable opening for adjusting cross direction coating uniformity. The nozzle may include a plurality of adjustment bolts spaced along the width of the nozzle for adjusting the opening of the nozzle. The adjustment bolts may be alternating push and pull adjustment bolts. Alternatively, the adjustable bolts are bolts having compound threads such that each bolt is capable of both pulling and pushing the adjustable opening of the nozzle. The substrate is preferably a moving web that defines the outer surface of a cooled drum. The apparatus further includes a radiation source positioned adjacent to the substrate for curing an organic monomer coating on said substrate. The radiation source may be an electron beam gun or an ultraviolet lamp.
