COATING FORMATION COMPOSITION AND METAL MATERIAL TREATMENT METHOD

WIPO Patent Application WO/2017/163446

A1

The present invention addresses the problem of providing a coating formation composition that enables formation of a lamination coating in which a chemical conversion coating and a surface treatment coating are laminated by applying and heating the coating formation composition on the surface of a metal material, without conducting a chemical conversion treatment on the metal material separately from the surface treatment, and that can impart excellent rust prevention properties to the metal material. The present invention also addresses the problem of providing a metal material treatment method. The present invention provides a coating formation composition characterized by comprising an alkoxysilane oligomer, a metal salt, and a solvent and characterized in that the solvent is water and/or a water-soluble organic solvent, and the content for the metal salt is 0.1-30 parts by mass with respect to 100 parts by mass of the alkoxysilane oligomer.
