"Chromate Free Surface Treated Metal Material"
Abstract: A surface-treated metal material not containing high environmental load hexavalent chrome, relatively easy to produce, and extremely superior in stain resistance, solvent resistance, alkali resistance, corrosion resistance is provided. The present invention is a chromate-free surface treated metal material characterized by having a coating film formed by coating an aqueous treatment agent containing an organic silicon compound (A) containing an alkylene group, siloxane bond, and cross-linkable functional group expressed by -SiR1R2R3 (wherein R1, R2, and R3 mutually independently express an alkoxy group or hydroxy group and any one of R1, R2, and R3 may be substituted by a methyl group) and an organic fluorine compound (B) containing a perfluoroalkyl group on the surface of a metal material and drying it.
