Introduction Polyurethane elastomers (PUEs) are a versatile class of polymers widely used in Coatings, Adhesives, Sealants, and Elastomers (CASE) applications due to their excellent mechanical properties, chemical resistance, and processability. The synthesis of PUEs involves the reaction between polyols and isocyanates, a process that often requires catalysts to achieve desired reaction rates, molecular weights, and...
