  • Publication number: 20210172072
    Abstract: Provided is a method for treating a surface of an aluminum article capable of imparting an effective anchoring effect to a surface of the aluminum article and enabling a strong chemical bond between the surface of the aluminum article and an organic material layer such as a coated resin layer or a laminated FRP applied to the surface without using a chemical solution that is not easy to treat. In the method for treating a surface of an aluminum article according to the present invention, the surface of the aluminum article is subjected to at least one of an etching treatment, a boehmite treatment, and a zirconium treatment, and then further subjected to at least one of a silane coupling agent treatment, an isocyanate compound treatment, and a thiol compound treatment.
