Abstract: The provided surface protection films include a plurality of layers in the following order: a first polymeric film that is exposed at a major surface of the surface protection film; a foamed adhesive; a second polymeric film; and a pressure-sensitive adhesive. The surface protective films withstand impacts and harsh outdoor conditions, and can be easily applied and removed while minimizing or eliminating the need to use personal protective equipment and volatile organic compounds.

Abstract: Briefly, the present disclosure provides a film, tape or outer layer of a composite part comprising: a) at least one layer comprising a crosslinked polymer selected from the group consisting of crosslinked polyurethane, crosslinked polyurea, and crosslinked mixed polyurethane/polyurea polymer; and in some embodiments b) an adhesive layer. In some embodiments the layer additionally comprises a non-crosslinked polymer forming a semi-IPN with the crosslinked polymer. In some embodiments the non-crosslinked polymer may be selected from the group consisting of polyurethane, polyurea, and mixed polyurethane/polyurea polymer. In some embodiments the crosslinked polymer may additionally comprise an acrylate-containing component.
