Bis-(Sodium Sulfopropyl)-Disulfide is a crucial component in copper electroplating, serving as a brightener to enhance the crystal refinement of the copper coating and improve current density in electroplating baths. With a recommended concentration of 10-50mg/L, this compound is widely used as a brightening agent in acid copper baths for both decorative and functional deposits. Its compatibility with various components of copper bath formulations, including non-ionic surfactants, polymeric amines, and other mercapto compounds, makes it an ideal choice for acid copper plating applications, particularly in decorative and functional coatings like printed circuit boards. For optimal results, Bis-(Sodium Sulfopropyl)-Disulfide can be used in conjunction with dye or in combination with other compatible compounds such as DPS and EXP2887.
