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.
