What is Stannous chloride?
Stannous chloride (CAS 7772-99-8), also known by its food additive designation E512, is an inorganic tin salt used as a reducing agent, catalyst, and stabilizer.
Where is Stannous chloride used?
- Food and beverage processing: E512 approved to prevent color degradation, effective in canned and preserved products such as white asparagus and certain seafood
- Textile and leather: mordant to fix dyes and improve color fastness on natural and synthetic fibers
- Plastics and polymer production: catalyst or catalyst precursor in polyurethane synthesis
- Printed circuit boards and packaging: tin plating and surface sensitization to prepare substrates for further metallic coating
- It prevents oxidative discoloration in processed foods and accelerates polymerization reactions.
Commercial specifications
- Packaging from small drums to bulk quantities
