Stannous chloride dihydrate

Stannous chloride dihydrate (CAS 10025-69-1), also known as tin dichloride, is a tin(II) salt used as a reducing agent, catalyst, and surface treatment chemical.

Where is Stannous chloride dihydrate used?

• Textile and leather processing: mordant that fixes dyes onto fiber substrates, improving color fastness and uniformity
• Printed circuit boards and electroplating: tin source and reducing agent for sensitizing non-conductive surfaces before metallization
• Plastics and polymers: catalyst precursor for polymerization and stabilizer component in PVC formulations
• Paper and packaging: flame-retardant treatments that reduce combustibility in coated substrates
• It donates electrons in controlled reactions for metal deposition, dye fixation, or polymer stabilization.

Commercial specifications

• Purity levels range from 98% to 99%+
