Dibutyltin Dilaurate (DBTDL) Catalyzed Polyurethane Elastomer Curing: A Comprehensive Review Abstract: Dibutyltin dilaurate (DBTDL) is a widely used organotin catalyst in the production of polyurethane (PU) elastomers due to its effectiveness in accelerating both the isocyanate-hydroxyl (NCO-OH) and isocyanate-water (NCO-H₂O) reactions. This review provides a comprehensive overview of DBTDL’s applications in PU elastomer curing, covering...
