Dibutyltin Dilaurate (DBTDL) as a Catalyst in the Synthesis of Specialized Polyurethane Materials: A Comprehensive Review Abstract: Polyurethane (PU) materials are ubiquitous due to their versatile properties and diverse applications. The synthesis of PUs relies heavily on catalysts to accelerate the reaction between isocyanates and polyols. Dibutyltin dilaurate (DBTDL) is a widely used organotin catalyst...
