Dibutyltin Dilaurate, DBTDL

Dibutyltin dilaurate (CAS 77-58-7) is a highly effective organotin catalyst, primarily used in the synthesis of polyurethane flexible foams, rigid foams, and elastomers, accelerating the reaction between isocyanates and polyols; it also acts as a room-temperature curing accelerator for silicone rubber; and as a heat stabilizer for PVC, improving the heat and weather resistance of the finished product. It is also used in the production of coatings, adhesives, and sealants, optimizing curing efficiency and product mechanical properties.
