| Bis-(sodium sulfopropyl)-disulfide Usage And Synthesis |
| Uses | Bis-(Sodium Sulfopropyl)-Disulfide is used as a brightener in copper electroplating,refining the crystal of the copper coating, and improving the current density in copper electroplating baths at a concentration of 10-50mg/L.Bis-(Sodium Sulfopropyl)-Disulfide used as a brightening agent for acid copper baths for decorative and functional deposits. It is functionally compatible with most components of typical copper bath formulation, such as non-ionic surfactants, polymeric amines and other mercapto compounds.Bis-(Sodium Sulfopropyl)-Disulfide for acid copper plating,decorative and functional availability coating (such as: printed circuit board). Bis-(Sodium Sulfopropyl)-Disulfide can be a typical copper formulations,such as non-ionic surfactant,polyamine and other thiol compounds in combination,can also be used in conjunction with the dye, if combined with DPS and EXP2887 with,you will get better results.
