HVEE, High-efficacious catalyzer for hard chromium plating, chromium plating intermediate

Effects and mechanisms

HVEE increases the cathode current efficiency to 22-26%, which is 2-3 times higher than the traditional standard chromium plating process.
It can be used in a wide current density range, which is about 30-90A/dm². It speeds up the deposition rate.
It does not contain fluoride, so LCD area of plating parts and anodes will not be corroded.
The hardness of deposit is 1000-1100HV; the number of microcrack is 400-1000/cm².
It has brightening, leveling, covering and throwing powers.
The stability of the bath is very good and easy to control and maintain.
