  • Applications

    Dibutyltin diacetate (CAS 1067-33-0) is primarily used as a tin-based catalyst in polymer processing, notably to accelerate curing in polyurethane resin systems and related foams, coatings, and elastomer formulations. It is also employed as a curing catalyst or accelerator for epoxy and polyester resin systems used in coatings and composites. In plastics processing, it may act as a processing aid and contribute to thermal stability during processing. Additionally, dibutyltin diacetate serves as an intermediate in the synthesis of other organotin compounds and can be used as a catalyst for crosslinking and curing in adhesive and coating formulations.
