07.04.2017 New catalyst with superior hydrolytic stability for polyurethane and organosilane applications Back Tools Bookmark Share Bismuth carboxylates can be effective alternatives to tin catalysts for accelerating the reaction of polyols with polyisocyanates. A serious drawback of bismuth carboxylates is their poor hydrolytic stability. Methods for improving the hydrolytic stability of bismuth carboxylate catalysts usually result in a corresponding decrease in activity. A unique bismuth catalyst has been developed that has excellent hydrolytic stability compared to conventional bismuth carboxylates. This new versatile catalyst is an effective accelerator for a variety of urethane applications and in addition shows efficacy in organosilane applications. Addressing potential regulatory labeling concerns, this new bismuth catalyst is tin-free and contains no 2-ethylhexanoic acid in the form of a free acid or as the metal carboxylate.
