• Product description :

  Characteristic: Item Description Appearance White to yellowish powder Assay ≥97% Solubility (at 20℃) In water approx.38%(very low in alcohols) Concentration in the bath 20-100mg/L Valid period(year) 2 Storage condition Stored in cool and dry place * Quality is strictly controlled under ISO system, with excellent chemical stability. Main application: SPS is used as a brightening agent in acid copper baths for decorative and functional deposits(i.e.printed circuit boards). SPS is functionally compatible with most components of typical copper bath formulations, such as non-ionic surfactants, polymeric amines and other mercapto compounds. An additional combination with dyestuffs is also possible. Very good results are obtained if used together with DPS and EXP2887. FENGFAN, TOP MANUFACTURER OF ELECTROPLATING CHEMICALS!
