DI-N-BUTYLTIN SULFIDE Chemical Properties,Usage,Production

Description

Dibutyltin Sulfide is a kind of sulfide. It can be used as a catalytic agent in some polymerization reaction. Dibutyltin sulfide has better catalytic activity and water-tolerant stability than DBTDL in waterborne polyurethane pre-polymerization system and can decrease the pre-polymerization time. It can also catalyze the ring-expansion polymerization of mesolactide. It is also an antioxidant and stabilizer for vinyl resins.
