Application of Butylstannic Acid in Polyurethane Catalyst

polyurethane (pu) is a type of polymer material with a wide range of uses. its applications cover soft foam, hard foam, elastomer, coatings, adhesives, sealants and many other fields. the synthesis of polyurethane is mainly achieved through the reaction of isocyanate and polyol. this process usually requires a catalyst to accelerate the reaction rate and ensure the performance of the product. butylstannic acid, as an efficient…
