Dibutyltin Dilaurate (DBTDL) Catalyst
Featured inIndustrial Catalysts
Dibutyltin Dilaurate (DBTDL) is an organotin Lewis acid catalyst widely used to accelerate the cure of polyurethane adhesives and sealants, RTV silicone sealants, and moisture-curing silane-modified polymer systems. It catalyzes both the urethane (NCO-OH) and urea (NCO-H2O) reactions, enabling faster room-temperature cure without significantly reducing pot life at normal use levels (0.01–0.1 phr). DBTDL is the industry-standard cure catalyst for one- and two-component PU and silicone systems.
