Application and Advantage
1. Green Products excluding Hexavalent Chrome; Simple wastewater disposal.
2. Even and esthetic coating with good covering power and dispersive ability.
3. No organic solvent in the plating solution; Excellent tolerance to Sulfate and Chloride ion.
4. It won’t cause bad plating result when power off; the deposition rate is faster than that of hexavalent
chromium plating.
5. Adopting graphite anode can improve the quality and stability of the bath.
