Product Application of Stannous Chloride Dihydrate CAS#10025-69-1
Stannous chloride dihydrate is widely used as a reducing agent, mordant, bleaching agent, and in tin electroplating processes. It is applied in the colorimetric determination of silver, lead, arsenic, and molybdenum, while also serving as a reducing agent and mordant in analytical and industrial applications.
This product is primarily used as the main salt in acidic tin plating baths, where bivalent tin provides high cathodic efficiency. The typical dosage ranges from 40–60 kg/L. It is also used in the glass mirror industry as a sensitizer for silver nitrate to achieve excellent coating brightness. In addition, when applied in ABS electroplating, the plating layer formed with this product demonstrates strong adhesion and is not easily detached.
