Description
Stannous Chloride Dihydrate 98%
Stannous Chloride Dihydrate 98% (CAS 10025-69-1, molecular formula SnCl2·2H2O) is a process chemical for electronics and metal finishing, where trace metal content and particle contamination matter as much as headline assay. China Chemicals supplies it at 98% min in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Tin(II) Chloride Dihydrate, Stannous Chloride, Tin Dichloride. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Sensitising step before electroless plating on plastics
- Immersion tin coating of printed circuit boards
- Reducing agent in silver mirror and glass coating
- Mordant in textile dyeing
- Stabiliser in fragrance and perfume manufacture
