Process for metallization of plastic surfaces

The invention aims at providing a practical process for chrome-free metallization of plastic surfaces by which a plating film adhering tightly to the surface of a plastics part can be formed and which is free from the deposition on a jig. A process for the metallization of plastic surfaces which is...

Zusammenfassung:	The invention aims at providing a practical process for chrome-free metallization of plastic surfaces by which a plating film adhering tightly to the surface of a plastics part can be formed and which is free from the deposition on a jig. A process for the metallization of plastic surfaces which is characterized by treating a plastics part with an etching fluid containing both a permanganate and an inorganic acid, treating the resulting plastics part with a potentiator fluid for the impartment of a catalyst which contains a compound exhibiting selective adsorption to functional groups exposedon the surface of the plastics part, imparting a catalyst to the treated plastics part with a catalyst imparting fluid, and then subjecting the resulting plastics part to metal plating.
