Application and Advantage
1. It’s green product without haxavalent chromium; the waste disposal is simple.
2. The coating color is uniform and bright with good cover ability and distribution.
3. Compared to traditional trivalent chromium the coating is whiter and harder, and has greater wear
resistance.
4. Current efficiency can achieve 30% while plating; Deposition rate is faster than that of haxavalent
chromium.
5. The working bath is stable with good impurity resistance, a better alternative to traditional haxavalent
process.
