Product Information

It is a brightening agent used for copper electroplating, especially acid copper baths. Copper layers deposited with SPS (CAS 27206-35-5) are very bright, levelled and ductile. 
SPS is used in copper plating in different industries - such as automotive parts and semiconductors. Copper baths have different goals including  changing appearance, enhancing electrical conductivity, or preventing corrosion. A combination of SPS (CAS 27206-35-5) and other additives (DPS and ZPS) can offer excellent results in functional plating, such as plating on PCB
