  • Applications

    Di(N-octyl)tin-S,S'-bis(isooctylmercaptoacetate) (CAS 26401-97-8) is primarily used as a heat stabilizer for PVC, helping prevent dehydrochlorination and color changes during high-temperature processing of halogen-containing polymers. It is also employed as a stabilizing/processing additive in coatings and inks formulated from plastics, serves as a catalyst in polyurethane polymerization and in certain epoxy or polyester resin systems, and can function as a precursor in organotin chemistry for plastics and adhesive applications.
