Uses of SPS (CAS 27206-35-5)      

SPS (CAS 27206-35-5), 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 - also manufactured by ALFA) can offer excellent results in functional plating, such as plating on PCB.

Our business is based on honesty and mutual-trust.Sincerely looking forward to establish long-term and mutual beneficial business relationship with worldwide customers.
