Title:
SURFACE-TREATING AGENT FOR ZINC-PLATED STEEL SHEET, AND ZINC-PLATED STEEL SHEET AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/105101
Kind Code:
A1
Abstract:
Disclosed is a chromium-free surface-treating agent comprising a resin compound having a specific bisphenol backbone, a cationic urethane resin emulsion, a silane coupling agent, an organic titanium chelate compound, a tetravalent vanadyl compound, a molybdic acid compound and water at a specified content ratio and having a pH value of 4 to 5. The chromium-free surface-treating agent enables the formation, on the surface of a metallic material, of a coating film that can impart excellent corrosion resistance to a bending-processed part of a steel sheet when applied onto the part, has excellent solvent resistance and exhibits excellent coatability after being defatted with an alkali. The chromium-free surface-treating agent exhibits excellent storage stability when prepared in the form of a one-part preparation.
