  • Method for depositing a first metallic layer onto non-conductive polymers
    Patent number: 9551073
    Abstract: The present invention relates to the etching, activation and deposition of a first metal or metal alloy layer onto non-conductive polymers. The non-conductive polymer is etched with an aqueous solution comprising 0.75 to 3.6 g/l permanganate ions in 60 to 80 vol.-% sulfuric acid, activating with a solution comprising a noble metal and depositing a first metal or metal alloy by immersion-type or electroless (autocatalytic) plating. The first metal or metal alloy layer obtained has a high adhesion on the non-conductive polymer and serves as a plating base for electroplating further metal and/or metal alloy layer(s) thereon.

  • PROCESS FOR METALLIZING NONCONDUCTIVE PLASTIC SURFACES
    Publication number: 20150307992
    Abstract: The present invention relates to a process for metallizing nonconductive plastics using an etching solution free of hexavalent chromium. The etching solution is based on an sulphuric acidic solution comprising a source of chlorate ions and a vanadium compound. After the treatment of the plastics with the etching solution, the plastics are metallized by means of known processes.

  • PROCESS FOR METALLIZING NONCONDUCTIVE PLASTIC SURFACES
    Publication number: 20150129540
    Abstract: The present invention relates to a process for metallizing nonconductive plastics using an etching solution free of both trivalent chromium and hexavalent chromium. The etching solution is based on an sulphuric acidic solution containing a source of chlorate ions. After the treatment of the plastics with the etching solution, the plastics are metallized by means of known processes.
