Abstract
1,251,213. Metallizing non-metallic surfaces; electro-plating. HOOKER CHEMICAL CORP. Sept.11, 1968 [Dec.28, 1967], No.43275/68. Addition to 1, 221, 111. Headings C7B and C7F. A non-metallic surface is pre-treated with elemental white or yellow P and then with a solution containing a) a metal salt or complex of a metal selected from Groups IB, IIB, IVB, VB, VIB, VIIB and VIII of the Periodic Table and b) a compound containing a stable anion selected from OH<SP>-</SP>, BR 3 H<SP>-</SP>, AlR 3 H<SP>-</SP> where R is alkyl, aryl or hydrogen. Only a small amount of the anion is added e. 0.05-10% volume OH- or 1 X 10<SP>-4</SP> to 4 x 10<SP>-1</SP> moles/1 of BH<SP>-</SP>4. Typical compounds containing these anions are NaOH, KOH, NaBH 4 , KBH 4 , sodium trimethyl or triphenyl or diphenyl methyl borohydride, lithium aluminium hydride, sodium trimethyl aluminium hydride. When R is alkyl it contains 1-10C atoms and 6-10C atoms when R is aryl. The preferred metal of the salt or complex is Cu, Ag, Au, Cr, Mn, Co, Ni, Pd, Ti, Zr, V, Ta, Cd, W, Mo. The salts may be those of mineral acids or organic acids containing 1-18C atoms and complexes may be formed with ammonia, quinoline dimethylglyoxine amines and pyridines. The salts or complexes may be in aqueous or non- aqueous solutions at a pH of 4-14. The P may be used as a vapour, liquid or solution in an organic solvent and the P treated surface may be treated with water, a liquid water compatible surfactant or an aqueous solution of the surfactant prior to treating with the solution of metal salt and stable anion (see Specification 1, 251, 214). The metal phosphide coating formed may be electro-plated e. g. with Ni and/or Cr either directly or an electroless coating may first be applied. The substrates may be mouldings, sheets, rods, fibres, films or fabrics of plastics filled or unfilled, and cellulosic or ceramics such as cloth, paper, wood, cork, cardboard, clay, porcelain, leather, glass, asbestos and cement. A large selection of plastics is exemplified.
