Abstract
A laminate includes a polycarbonate substrate and an ultraviolet hard coat film disposed on the polycarbonate substrate. The ultraviolet hard coat film may include a polyethylene terephthalate (PET) layer, an adhesive interposed between the PET layer and the polycarbonate substrate, and an exterior hard coat disposed on the PET layer opposite the polycarbonate substrate. The exterior hard coat may include UV stabilizers. The laminate may include additional ultraviolet hard coat films stacked on the ultraviolet hard coat film. The laminate may be thermoformed into the shape of a curved vehicle windshield.
