PHOTOCATALYST PRECOATED MOLDING MATERIAL, PHOTOCATALYST PRECOAT MOLDING, AND PHOTOCATALYST PRECOATED FIN

摘要

PROBLEM TO BE SOLVED: To provide a photocatalyst precoated molding material which does not use harmful chromium, has a primary coat of a non-chromate treatment type, can withstand molding, is hardly peelable, enables a photocatalyst to be homogeneously applied on necessary parts when molded, and is excellent in productivity; and a molding and a photocatalyst precoat fin both prepared by using the same. SOLUTION: This molding material comprises a metal substrate 1 formed from aluminum or an aluminum alloy, a primary coat 2 comprising a non- chromate reaction type treatment layer formed on the surface of the substrate 1, and a photocatalyst layer formed on the primary coat 2.
