Japanese Patent JP6510670

Kind Code:

B2

Abstract:

[Problem] To provide: an aqueous surface treatment agent that is for a zinc plated steel material or a zinc-based alloy plated steel material, that has satisfactory properties such as corrosion resistance, post-degreasing corrosion resistance, coating adhesion, post-degreasing coating adhesion, blackening resistance, condensation whitening resistance, treatment agent stability, actual device operability, and the like, and that can form a coating having excellent stack whitening resistance and filament tape resistance; a coating method using the treatment agent; and a coated steel material obtained using the method. [Solution] This aqueous surface treatment agent for a zinc plated steel material or a zinc-based alloy plated steel material is obtained by blending a cationic polyurethane resin (A), a cationic phenolic resin (B), a silane coupling agent (C), an acetylacetone complex of titanium (D), an olefin wax (F), a vanadium compound (E), an acetic acid component (G), a phosphoric acid component (H), and water.
