Cyanide Copper Bath JE550

The Cyanide Copper Bath JE550 is suitable for rack and barrel plating.

Thanks to its excellent throwing power and high adhesion strength, the electrolyte is frequently used as an undercoat before subsequent electroplating processes.

The deposited copper layers are fine-grained and slightly bright, providing excellent adhesion between the base material and the final coating.
