Abstract
Reflective aluminum trim for use in automobiles, trucks, boats and a variety of household and industrial appliances is produced by forming aluminum strip into a desired shape, followed by selective application of a fluoropolymer protective coating to only a partial portion of the show surface of the shaped strip and the application of a thermoplastic to the portions of the show surface not covered by the protective coating. The resulting trim piece has a highly reflective aluminum show surface which has a high distinctness of reflected image. The thermoplastic is preferably co-extruded onto the shaped aluminum strip using an adhesive to bond the thermoplastic directly to an un-coated portion of the aluminum surface. Prior to application of the thermoplastic, a single heating step may be used to cure both the protective coating and the adhesive.
