Copper plating brightener, used in combination with surfactants such as polyether and wetting agent, and can also be used in combination with other sulfur-containing brighteners to obtain a bright and ductile coating. It can also be used for the electroless plating of precious metals and as a stabilizer for electroplating. DPS is a brightener in the medium current density area. This product was first introduced into China by the German RASCHIG company. Its main function is to emit light quickly and the stability of the plating solution is good. Rough use method: used with SPS. For high-quality SPS, SPS and DPS are used in accordance with 1:1, and for ordinary SPS on the market, because it contains DPS components, the ratio must be adjusted. After adding DPS, it can reduce the electroplating failure, it can adjust the balance of SPS, M, N, and can complex monovalent copper ions.
