Umicore Copper 838 Copper Electrolyte

Umicore Copper 838 Copper Electrolyte

Cyanide-free alkaline copper electrolyte for barrel applications

Umicore Copper 838 is a cyanide-free alkaline copper electrolyte. By dispensing with highly toxic cyanide in the electrolyte, the protection and safety of plant operators and the environment is ensured to a large extent.
 
The deposited coatings are fine-grained, ductile and appear silky matt to bright over a wide current density range, depending on the brightness of the brightener. 

Umicore Copper 838 is used in barrel plating. In addition to the common metallic base materials such as non-ferrous metals, iron or steel, zinc die-cast alloys can also be directly copper-plated with appropriately adapted pretreatment. 

Umicore Copper 838 Brightener 1 prevents pores and has a slight brightening effect. Furthermore, the addition extends the gloss range and improves the fine grain size.
