Title:
METHOD OF TREATING SURFACE OF METAL BASE, METALLIC MATERIAL TREATED BY THE SURFACE TREATMENT METHOD, AND METHOD OF COATING THE METALLIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2008/029926
Kind Code:
A1
Abstract:
A method of treating the surface of a metal base which is conducted prior to cationic
electrodeposition coating and is used for improving throwing power in the cationic
electrodeposition coating; a metallic material treated by the surface treatment
method; and a method of coating this metallic material. The metal surface treatment
method, which improves throwing power in cationic electrodeposition coating,
comprises: a metal base surface treatment step in which the surface of a metal
base is treated with a surface treatment composition comprising zirconium ions
and/or titanium ions and at least one adhesion promoter selected from the group
consisting of (A) silicon compounds, (B) adhesion-promoting metal ions, and
(C) adhesion-promoting resins to form an anticorrosive coating film; and a post-treatment
step in which all or part of the metal base which has undergone the surface treatment
step is treated with a given solution.
