Abstract
Protective laminate films protect an underlying window surface from scratches or other damage. The laminate films generally include a substrate having a scratch resistant coating adhered to one side and an adhesive layer adhered to an opposite side. Adhesion promoter and primer layers may be provided to enhance adhesion of the scratch-resistant coating to the surface. Each layer is transparent such that, when applied to a surface, the laminate film does not significantly impact or reduce optical clarity. Each layer may also be flexible so that the laminate films can be molded to a curved surface. Generally, the scratch resistant coating protects the laminate film from scratching or other damage, such as from debris or impacts. The substrate provides structural integrity to the laminate film and may provide some impact dispersion. The adhesive layer, in addition to adhering the laminate films to the surface, may also provide significant impact resistance that protects the surface from cracks or damage due to debris or impacts.
