Surface preparation for adhesive bonding

摘要

A method for preparing an aluminum surface for adhesive bonding which consists essentially of the steps of: (a) preparing an aqueous solution of an epoxy-functional silane; (b) degreasing a selected area of the surface; (c) wet abrading the selected area using the aqueous epoxy silane solution; (d) removing any residue from the selected area; (e) allowing the surface to air dry; (f) wiping an alcoholic solution of an amino-functional silane onto the selected area; and (g) allowing the surface to air dry.
