Trim component including a metalized polyester film and substrate having curled edges

摘要

A metalized polyester film for application to a substrate to be used as a trim component for automobiles and the like. The film is comprised of a thermally stable extensible polyester carrier for supporting multiple layers of metallic and thermoplastic coatings. Prior to application of a metallic coating, the film is cleaned by means of exposure to an inert gas such as argon in order to remove moisture and other impurities. A layer of aluminum or other metal is then deposited on the carrier film thereby forming a superior bond with the cleaned surface. A tie coat primer is applied over the aluminum which is followed by an adhesive. The metalized film is adhesively applied to a formable substrate which is configured into an end component part by means of vacuum forming or pressure forming. The formed laminated substrate is next attached to a piece of support plastic, wherein the composite part can be applied as trim. A protective lacquer coat is applied to the polyester film as a final step. The end product trim component is extremely wear-resistant and the polyester film is suitable for embossing. In an alternate embodiment of the invention, lamination to the formable substrate is eliminated from the process and the metalized film is applied directly to an extruded plastic member configured to the shape of the end product.
