Functions and Uses：
1. It’s the environmental-compliant product, free of hexavalent chromium, only simple waste water treatment required.
2. No adverse consequences in case the electric power sudden off.  The deposition speed is faster than hexavalent chromium.
3. The produced deposit is with the beautiful and homogenous dark black appearance as well as excellent coverage and leveling.
4. The solution does not contain the organic solvents and the chelating agents, and with high tolerance to the sulfate and chloride ion.
5. Suitable for all kinds of POP, metal, and decorative plating.
