  • Inhibitor Composition for Racks When Using Chrome Free Etches in a Plating on Plastics Process
    Publication number: 20180044813
    Abstract: The invention relates to an aqueous inhibition composition for the inhibition of electrochemical metal plating on polymer surfaces, said inhibition composition comprising an inhibition agent selected from the group of compounds having at least one sulfur and at least one nitrogen atom as well as to a method for the inhibition of an insulated surface of a rack area. The inventive inhibition composition is capable to provide a solution for prohibiting unintended metallization on insulated areas of the racks when non-chromic etching is utilized for plating on plastics processes.

  • Galvanic bath and process for depositing zinc-based layers
    Patent number: 8282806
    Abstract: The preceding invention concerns a galvanic bath as well as a method for depositing a zinc-bearing layer onto a substrate surface. According to the invention, it is provided that the galvanic bath be divided into at least two cell chambers, in which the division occurs by means of a cation-exchange membrane and one cell chamber includes an acidic deposition-electrolyte and the other cell chamber includes a neutral or acidic anolyte. The acidic anolyte here is at least partially removed from the cell chamber containing it and is stripped of the foreign metal ions contained in it by means of a cation-exchange arrangement.
