Product Description of Stannous chloride dihydrate CAS#10025-69-1

Tin(II) chloride dihydrate is industrial grade with purity ≥99%, as white crystalline powder with faint hydrochloric acid odor. It melts at 37.7℃ and decomposes at 623℃ without boiling, featuring negligible vapor pressure at 25℃ and relative density of 2.71 at 20℃. It is soluble in water with easy hydrolysis, soluble in ethanol and ether, but insoluble in benzene. Stable under regular conditions, it should be stored separately from strong oxidants and strong bases.

Product Application of Stannous chloride dihydrate CAS#10025-69-1

Stannous chloride dihydrate is extensively used as a reducing agent, mordant and bleaching agent, as well as in tin electroplating. It enables colorimetric determination of silver, lead, arsenic and molybdenum, and acts as a reducing agent and mordant for analytical and industrial purposes. It serves as the main salt in acidic tin plating baths, with divalent tin ensuring high cathodic efficiency at a typical dosage of 40–60 kg/L. It is also used as a sensitizer for silver nitrate in glass mirror manufacturing to deliver superior coating brightness. Furthermore, in ABS electroplating, it forms plating layers with firm adhesion and excellent anti-peeling performance.
