Bis-(Sodium Sulfopropyl)-Disulfide (SP/SPS) is a white or light yellow solid compound with the chemical formula C6H12O6S4Na2 and CAS number 27206-35-5. This organosulfur derivative is supplied by Wuhan Silworld Chemical Co., Ltd. in assay purities of 85% and 95%, as confirmed by the supplier’s technical data. Its primary function is as a brightener in acidic copper plating baths, where it enhances the lustre and uniformity of decorative and functional copper deposits, particularly in printed circuit board manufacturing.
The compound is chemically compatible with common copper bath additives, including non-ionic surfactants, polymeric amines, and mercapto-based compounds, allowing seamless integration into existing formulations. It can also be paired with dyestuffs or other brighteners such as DPS and EXP2887 to achieve tailored surface finishes. Standard industry practice for such additives includes testing for plating uniformity, brightness, and adhesion, with typical performance benchmarks measured via Hull cell testing or cyclic voltammetry.
Industrial buyers source this additive for electronics manufacturing, particularly PCB production, where consistent deposit quality is critical. Wuhan Silworld Chemical Co., Ltd. offers the product in bulk quantities, with packaging and trade terms available upon direct inquiry. The compound’s stability in acidic media and its role in improving deposit smoothness make it a preferred choice for high-precision applications in the electroplating sector.
