Synocat® T-12 DBTDL

Dibutyltin dilaurate, CAS 77-58-7, PU catalyst, organotin catalyst, PVC heat stabilizer

Synocat® T-12 DBTDL (Dibutyltin Dilaurate) is a high-performance organotin compound renowned for its strong catalytic activity. It is a multifunctional additive primarily serving as a catalyst for polyurethane (PU) formation, a heat stabilizer for PVC, and a curing promoter for silicone sealants. It is soluble in common organic solvents (alcohols, ketones, aromatics) and insoluble in water, making it ideal for various solvent-based and reactive systems that require efficient acceleration of condensation and curing reactions.
