Bismuth and Zinc Catalysts

Environmental protection is the development trend of the polyurethane industry today. Due to the adverse effects of compounds such as lead, mercury, and tin on human health and the environment, which has been strictly restricted in polyurethane industry. Polyurethane eco-friendly catalysts mainly include organic bismuth, organic zinc, and zinc bismuth mixed catalysts, which can be widely used in the production of polyurethane coatings, resins, slurries, adhesives, sealants, elastomers, and other PU industries. They are an excellent choice to replace toxic lead mercury tin catalysts.
