Title:
CHROMATE-FREE SURFACE-TREATED METAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2010/061964
Kind Code:
A1
Abstract:
Disclosed is a surface-treated metal material which does not contain hexavalent chromium that has a high environmental load, can be produced relatively readily, and has excellent stain-proof properties, solvent resistance, alkali resistance and corrosion resistance. Specifically disclosed is a chromate-free surface-treated metal material characterized by having a coating film formed thereon, wherein the coating film is produced by applying an aqueous treatment solution on the surface of a metal material and drying the aqueous treatment solution, wherein the aqueous treatment solution comprises an organosilicon compound (A) containing an alkylene group, a siloxane bond and a cross-linkable functional group represented by the formula -SiR1R2R3 (wherein R1, R2 and R3 independently represent an alkoxy group or a hydroxy group and at least one of R1, R2 and R3 may be substituted by a methyl group) and an organofluorine compound (B) containing a perfluoroalkyl group.
