  • Electrolytic treatment device for preparing plastic parts to be metallized and a method for etching plastic parts
    Patent number: 11603595
    Abstract: The present invention refers to an electrolytic treatment device having an anodic compartment comprising a non-chromium (VI) etching solution to be treated and immersed therein an anode. The anodic compartment is separated by a membrane from a cathodic compartment comprising a cathodic solution comprising an inorganic acid, wherein the anode and the cathode are used comprising or consisting of a ternary or higher Pb alloy with Sn and at least one further metal selected from the group consisting of Sb, Ag, Co, Bi and combinations thereof. Moreover, a method for etching plastic parts is provided as well.
