Stannous chloride dihydrate

Stannous chloride dihydrate (CAS 10025-69-1) is an inorganic tin salt supplied as a white crystalline solid, also known as tin dichloride dihydrate or tin chloride dihydrate. It carries no assigned E-code and is identified under EC number 600-045-1 with HS code 28273910.

In textile and leather processing, stannous chloride acts as a reducing agent and mordant, fixing dyes to fibres by forming stable coordination complexes with metal-based colorants. In plastics and polymer formulations, it functions as a catalyst for condensation reactions and contributes flame-retardant properties by promoting char formation and interrupting combustion pathways.

This material is available in technical and high-purity grades, with supply subject to REACH registration requirements applicable to EU importers and downstream users. Standard packaging includes fibre drums and multi-layer bags; documentation typically covers SDS, CoA, and country-of-origin certification upon request.
