PROCESS FOR METALLIZING NONCONDUCTIVE PLASTIC SURFACES

摘要

Metallizing electrically nonconductive plastic surfaces of articles involves: (A) treating the plastic surface with etching solutions; (B) treating the plastic surface with a solution of a colloid or of a compound of a metal; and (C) metallizing the plastic surface with a metallizing solution, where the etching solutions comprise at least one acidic etching solution and at least one alkaline etching solution, and that each of the etching solutions comprise a source for permanganate ions.
