Yourun is one of the companies that produce the largest variety of organic metal catalyst in the world. Besides the bismuth and zinc catalysts, Yourun also produce TCAT series of organotin catalysts, which are widely used in polyurethane industry.
Characteristics of TCAT series special organic tin catalysts:
High catalytic activity, strong activity for the reaction of hydrogen with isocyanates.
Sensitive to moisture, widely used in moisture curing systems, including polyurethane moisture curing, MS adhesive and sealant, etc.
widely used in polyurethane foam system as gel catalyst.
High hydrolysis resistance, with higher stability in aqueous systems than ordinary metal catalysts.
Good compatibility with various PU systems, without affecting the transparency of the system.
