Abstract: Surfacing films and related processes are provided. These films include a first clear coat layer comprising a first crosslinked polyurethane that is the reaction product of an isocyanate; a polyol selected from the group consisting of: a caprolactone polyol, polycarbonate polyol, a polyester polyol, acrylic polyol, polyether polyol, polyolefin polyol, and mixtures thereof; and a hydroxy-functional silicone poly(meth)acrylate; a second clear coat layer comprising a crosslinked polymer that is essentially free of hydroxy-functional silicone poly(meth)acrylate; a bulk layer comprising a thermoplastic polyurethane; and an adhesive layer. The provided films overcome the problem of migration of solvents and other impurities into the polyurethane bulk layer because the clear coat layer is cured, and solvents removed, prior to the coating of the polyurethane bulk layer. Manufacturing of these films can provide substantially faster line speeds and reduced waste.
