PPS is the starting material for preparing brightener in Watt bright nickel plating. It is an efficient brightener (secondary brightener) and leveler. Because of its high purity, it will not bring harmful impurities or salts to the tank solution, and it will be used for a long time without any extension problem. It is usually used in conjunction with saccharin, one or more acetylene compounds and wetting agents. This process can make the nickel plating layer particularly bright, flat and good ductility. It can also be used in the case of no flow of electrolyte.
