Dibutyltin Bis(2-ethylhexanoate) (DBTEH) Catalyst
Dibutyltin Bis(2-ethylhexanoate) (DBTEH) is an organotin catalyst with lower toxicity and improved hydrolytic stability compared to DBTDL, used to accelerate cure in polyurethane and silicone adhesive and sealant systems. Its reduced tendency to hydrolyze makes it more suitable for moisture-sensitive formulations that require extended storage stability. DBTEH provides excellent catalytic activity for NCO-based reactions and is compatible with both solvent-free and solvent-borne PU systems.
