    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.

    Abstract translation: 简而言之,本公开提供了复合部件的膜,带或外层,其包括:a)至少一层包含交联聚合物的交联聚合物,所述交联聚合物选自交联聚氨酯,交联聚脲和交联的混合聚氨酯/聚脲聚合物; 并且在一些实施方案中,b)粘合剂层。 在一些实施方案中,该层另外包含与交联聚合物形成半IPN的非交联聚合物。 在一些实施方案中,非交联聚合物可以选自聚氨酯,聚脲和混合的聚氨酯/聚脲聚合物。 在一些实施方案中,交联聚合物可另外包含含丙烯酸酯的组分。
