ABSTRACT:
A method for achieving a high gloss finish on a compression molded substrate, molded with or without vacuum, in which the substrate includes a hollow filler material and has a specific gravity of not more than 1.4, including the steps of heating at least the surface of the substrate, to a temperature above the melting temperature of a subsequently applied coating powder and applying a first layer of powder to the heated surface, and if necessary, elevating the temperature of the surface and maintaining the temperature of the heated surface above the curing temperature of powder by infrared radiation or by forced heated air for a time period sufficient to cure the powder and then, if desired, subsequently electrostatically applying a second coating to at least a portion of the first film.
