PROCESS FOR METALLIZING NONCONDUCTIVE PLASTIC SURFACES

摘要

Metallizing electrically nonconductive plastic surfaces of articles involves: a) etching the plastic surface with etching solution; b) treating plastic surface with a solution of a metal colloid or compound of a metal selected from metals of transition group I and transition group VIII of the periodic table of the elements; and c) metallizing the plastic surface with a metallizing solution; where the etching solution comprises a source for permanganate ions and an acid in concentration of 0.02-0.6 mol/l based on monobasic acid.
