Hard chromium catalyst

CR-2 high-efficiency hard chromium electroplating process can produce micro-crack chromium plating, with high efficiency and little anodic corrosion. The coating position and metal distribution of this process are superior, the high current density area is not easy to scorch, and it has a complete soluble catalytic system.
