DOWN DOC  Triclos ® chromium and trivalent chromium plating process
Triclos ® chromium and trivalent chromium plating process
Name: Triclos ® chromium and trivalent chromium plating process
Origin: Germany
Packing: 25Kg/Dr

I、Features
1. Environmentally friendly products, hexavalent chromium-free, simple and wastewater treatment.
2. Uniform color, appearance, with good coverage ability and the ability to have degrees.
3. Bath does not contain organic solvents; of chloride and sulfate of good tolerance.
4. Electroplating when power would not have adverse consequences, the deposition rate faster than the hexavalent chromium.
5. OPASS Germany used to provide the graphite anode, improve quality and increase the stability of the bath.
