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.
