Dibutyltin Dilaurate

Dibutyltin Dilaurate (DBTDL) acts as a Lewis acid catalyst, accelerating the reaction between polyols and isocyanates in polyurethane systems. It enables faster gelation and balanced crosslinking, improving coating hardness and elasticity. Available in liquid form with controlled metal content, DBTDL is compatible with polyester, polyether, and acrylic systems. It delivers high catalytic efficiency even at low dosages, ensuring smooth surface finishes and consistent curing in foams, coatings, and adhesives.
