Color passivation agent for zinc-nickel alloy plating

Zn-324 is a colorful trivalent chromium passivation film for electroplating zinc-nickel alloy workpieces. This process can produce bright, light-colored (color between yellow and green) film, and has high corrosion resistance. For traditional multicolored hexavalent chromium film passivation, this treatment provides users with a safer choice. It can be applied to hanging and rolling process applications.
