Aluminum Alloy Acid Etch HN-AC is especially suitable for corrosion of pre-treatment of aluminum and aluminum alloy parts. It can provide even corrosion without damaging the parts. It can remove the inorganic film from surface and provide good adhesion for subsequent plating process. During the process, it react gently and is easy to control. The even and fine grained surface, formed by HN-AC, is especially suitable for pre-treatment of non-cyanide zinc deposition. The result will be better if it is used together with HN-200 non-cyanide zincate process.
