  • Patent number: 9617644
    Abstract: The present invention relates to a method for direct metallization of non-conductive substrates as well as a conductor solution used in such a method. According to the invention, it is proposed to contact a non-conductive substrate surface after activation by a noble metal colloid-containing activator solution with a conductor solution, which comprises a metal that is reducible by a metal of the activator solution, a complexing agent and a reducing agent.
    Type: Grant

  • Patent number: 9222189
    Abstract: A process for treating the surface of a metal substrate comprising a constituent metal selected from the group consisting of Cr, Cu, Mn, Mo, Ag, Au, Pt, Pd, Rh, Pb, Sn, Ni, Zn, in some cases Fe, and alloys of these metals. An anodic potential is applied to the metal surface in an electrolytic circuit comprising the metal surface, a cathode, and an electrolytic solution that is in contact with the metal surface and in electrically conductive communication with the cathode. The electrolytic solution may contain an electrolyte comprising anions of phosphate, phosphonate, phosphite, phosphinate, nitrate, borate, silicate, molybdate, tungstate, carboxylate, oxalate and combinations thereof. The anion may comprise a polymer having a pendent moiety selected from the group consisting of phosphate, phosphonate, phosphite, phosphinate, sulfate, sulfonate, carboxylate and combinations thereof.
