Abstract: A surfacing film is provided that includes a plurality of layers in the following order: an outer layer comprised of a reaction product of a two-part curable fluoropolyurethane composition including a polyisocyanate and at least one polyhydroxy-functional fluoropolymer, optionally a primer layer comprising a polyurethane; and a base layer. Advantageously, the surfacing films can display superior gloss, mechanical durability, chemical/stain resistance, easy cleaning performance, and weather aging stability compared with conventional surfacing films.

Abstract: Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30° C.; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness.

Abstract: Provided are one-part, shelf-stable polyurethane aerosol compositions, and related articles and methods. When sprayed onto a substrate and dried, these compositions provide polyurethane films. These polyurethane films display improved moisture resistance, optical clarity, and weatherability compared to known aerosol compositions, particularly in adverse environmental conditions. The compositions generally include an aqueous polyurethane dispersion containing a urethane moiety obtained by reacting (i) a polyol or thiol having isocyanate-reactive functional groups, (ii) a neutralized water-solubilizing compound, and (iii) a diisocyanate and optionally a silane terminal group; a propellant; and optionally one or more additives.
