Amine Catalyst. Toyocat is the trade name of Tosoh's specialty amine catalysts for polyurethanes. Amine catalysts balance the various reactions during the formation of polyurethane, help to reduce foam defects and influence the physical characteristics and quality of the final product. Alkyl tin carboxylates, oxides and mercaptides oxides function as mild Lewis acids in accelerating the formation of polyurethane. As acidic conditions are required to proceed, acid catalysts are recommended. In addition, amines are also used for closely related polyurethane reactions: biuret and allophanate reactions/trimerisation and polyurea forming. Triphenylbismuth itself does not catalyze the isocyanate-hydroxyl reaction, but rather is hydrolyzed in presence of acid to a bismuth salt, which functions as catalyst. When used as a 8 We were interested in a catalyst with high selectivity for the isocyanate- hydroxyl reaction and its applications in two component water borne polyurethane formulations. Organic Catalyst. Use of Basic Catalysts. The side reactions are minimized so the end products have better color and odor properties because fewer by-products are formed, there is no need for refining to remove the catalyst residues and the equipment corrosion is eliminated. Dabco PT303 catalyst is a high-efficiency polyurethane composite tertiary amine, which can strongly catalyze the urea (water-isocyanate) reaction of hard spray polyurethane foam, thereby greatly increasing the foaming reaction time.
