  • Applications

    Dodecyltin tris(isooctyl thioglycolate) (CAS number: 67649-65-4) is an organotin complex bearing three isooctyl thioglycolate ligands and is primarily used as a heat stabilizer for PVC and related chloride-containing polymers. In the polymer industry, it is commonly evaluated as a catalyst for polyurethane formulations (foams and coatings) and may be incorporated into paint and ink formulations to improve thermal stability and process durability. It also serves as an intermediate in the synthesis of specialty organotin compounds and can function as a stabilizer or catalyst in adhesive systems and coating matrices. These applications span plastics, coatings, and adhesive industries, with usage governed by local regulations and formulation limits.
