Two-part aqueous metal protection treatment

摘要: A two-part metal protection composition includes: an aqueous treatment conversion coating component that includes admixture of acid and a forming component; protective is applied over treated with the blister suppressing agent organic film component. The may contain accelerator, such as hydroxylamine. In preferred embodiment, oxidizing one or more nitroguanidine; aromatic nitrosulfonates, Naphthol Yellow S; picric (trinitrophenol). method for treating metallic surface (a) applying described above; (b) component, above, to has at least been partially bonding elastomeric substrate surface; primer composition, (c) adhesive overcoat effect substrate.
