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 is a surfacing film that includes a plurality of layers. The layers include a first clear coat layer made from a crosslinked polyurethane that is a reaction product of a reactive mixture including an isocyanate and a polyol containing a styrene repeat unit and a hydroxyl-containing (meth)acrylate repeat unit. The surfacing film further includes a bulk layer made from a thermoplastic polyurethane and an adhesive layer. Optionally, the surfacing film includes second clear coat layer, which can be made from a polyurethane that is at least partially crosslinked. The resulting surfacing film can display high stain resistance, high peel strength, superior scratch resistance and self-healing properties.
