Abstract

A process for coating a surface comprising the steps of admixing a plastic polymer in the form of a powder with a pigment to form a paint precursor; melting the paint precursor to form a liquid paint; and applying said liquid paint to the surface to be coated, is described. In coating plastics, the plastic material could be a thermoplastic material. Preferably, the powdered plastic of the paint precursor is the same polymer as the plastic material to be coated.The present invention is directed towards providing a cheaper and more versatile process for coating various surfaces including plastic materials. Apparatus for the process is also described.
