Stannous pyrophosphate is colorless or white powder with a density of 4.009g/cm3. It is insoluble in water, soluble in acid. Our stannous pyrophosphate is of high purity, unique crystal structure, extremely low Fe, Pb, and As contents, easy to be chelated with potassium pyrophosphate, efficiently controlling Sn2+ oxidation, excellent polarizing and current distribution ability of plating solution.
Stannous pyrophosphate is mainly used in non-cyanate tin plating, soluble in potassium pyrophosphate solution to form a stable K6[Sn(P2O7)2 ] chelate complex.
