Rack Copper Sulfate Plating Process
★Use and characteristics
1. Quick bright and good level-up, excellent throwing power at low current densities, low hardness of bright cooper plating is suited to soft cloth polishing.
2. It can get mirror bright deposits at wide current density range, no hard spot and rough on the deposits.
3. It is necessary to fall the film, so as not to affect the cementing property with the nickel deposits,
