Abstract
A process for manufacturing a metallized part comprises the following steps. A part is provided made from a substrate material selected from the group consisting of thermoplastic urethane (TPU), TPU alloys, polyester alloys, nylon, thermoplastic olefins (TPO) and aluminum. A single protective layer (combined primer/basecoat) is spray deposited, flashed and cured over the substrate. Over the combined primer/basecoat layer, a layer of corrosion prone metal is vacuum deposited to form a discontinuous film covering the combined primer/basecoat layer. A layer of clear resinous protective dielectric topcoat is spray deposited and cured to completely cover the layer of vacuum deposited corrosion prone metal material and fill channels formed in the discontinuous film layer.
