  • Hydrophilizing agent, hydrophilizing fluid, and method of hydrophilizing
    Patent number: 6987143
    Abstract: A hydrophilizing agent comprising: (a) a hydrophilic polymer which is a copolymer of N-vinylacetamide with a polymerizable monomer having a COOX group (wherein X means hydrogen, an alkali metal atom, or an ammonium salt); (b) a water-soluble urethane resin; and (c) inorganic silica. It imparts hydrophilicity and corrosion resistance to the surface of a metallic material.
    Type: Grant
    Filed: January 15, 2001
    Date of Patent: January 17, 2006
    Assignee: Henkel Kommanditgesellschaft auf Aktien
    Inventors: Kazuya Nakada, Motoya Kawaguchi
  • Treating agent for imparting hydrophilicity and high corrosion resistance, hydrophilizing fluid, and method of hydrophilizing
    Publication number: 20030092812
    Abstract: A highly corrosion-resistant hydrophilization agent, characterized in that it contains (a) a hydrophilic polymer, that is, a copolymer of N-vinylacetamide and a polymerizable monomer having a COOX group (in the formula, X means hydrogen atom, alkali metal atom or ammonium salt), (b) an organic cross-linking agent, and (c) at least one metal compound selected from Ti, V, Cr, Mn, Co, Zn, Zr, Mo, Ce and W.
