TCAT-NS01 is a new generation of highly efficient chelated tin catalyst designed for reactions involving silicones, polyurethanes, and polyesters. It exhibits catalytic activity significantly higher than that of traditional dibutyltin dilaurate (T-12). When used in silane-based systems, it offers the following characteristics: ? High catalytic activity and rapid curing efficiency, promoting deep-section curing. It effectively accelerates the hydrolysis and polycondensation of silane- terminated polymers, facilitating quick surface drying and through-curing, with a notable effect on the deep-section curing of thick-film applications. ? High catalytic efficiency at low temperatures, addressing the issue of slow curing during winter. It overcomes the significant loss—or even total disappearance—of catalytic activity often experienced with traditional T-12 catalysts at low temperatures.

TCAT-S029 is a delayed-action, hydrolysis-resistant organotin catalyst developed to address the issue of conventional organometallic catalysts gradually losing their activity—and failing to remain stable during long-term storage—when exposed to trace amounts of water, acids, or bases. Similar to imported organotin catalysts such as UL-29 and KOSMOS 16, TCAT-S029 offers the following characteristics: ? Excellent delayed-action properties with an extended flow period. As a delayed-action catalyst, TCAT-S029 provides a significantly longer duration during which the material remains in a low-viscosity, flowable state compared to T-12. ? A heat-activated gelling catalyst with rapid post-curing. It exhibits low catalytic activity at room temperature, which increases significantly as the temperature rises. It strongly promotes the reaction between -NCO and -OH groups. This characteristic is ideal for molding processes that require rapid curing at elevated temperatures, such as the pultrusion of high-strength polyurethane composites, the Reaction Injection Molding (RIM) process for automotive protective panels, and the production of complex structural components or large cast parts.

BCAT-E16 is a precisely engineered organic bismuth catalyst that embodies the typical characteristics of eco-friendly bismuth-based catalysts: It is safe and environmentally friendly, serving as a potential replacement for organic lead, mercury, or tin catalysts in certain applications. It offers superior hydrolytic stability compared to T9. It promotes the NCO/OH reaction; in both solvent-borne and waterborne polyurethane systems, it can help mitigate side reactions between water and NCO groups, thereby reducing CO2 generation. However, its ability to suppress the reaction between isocyanates and water is less pronounced than that of catalysts such as CUCAT-HA, CUCAT-HAA, or CUCAT- PD. It exhibits excellent compatibility and can be used either independently or in combination with other catalysts.

CUCAT series of Non Foaming PU Catalyst?are ideal catalysts substitute for mercury catalyst in non foaming CASE field. Organic mercury catalyst has four unique characteristics: activity is slow before but fast after, no foaming and high performance. In particular, the characteristic of no foaming is the unique symbol of organic mercury. It is generally used in various isocyanate and active hydrogen systems, but the high toxicity of organic mercury makes it almost banned in the world. Years of research have proved that it is impossible to completely replace organic mercury with only one environmental protection catalyst. CUCAT series catalysts?are developed by subdividing the application of organic mercury in various polyurethane systems. The catalytic effect of organic mercury can be achieved or even exceeded by selecting different CUCAT catalysts for different systems. Conventional catalysts in polyurethane industry basically have a strong catalytic effect on the reaction between isocyanate and water, which is difficult to meet the requirements of no bubbles in most products of CASE field. At present, it is recognized that organic bismuth, whose catalytic properties are closer to that of organic mercury, can not avoid foaming, bulging and cracking even if a more stringent moisture control production process is adopted, for only controlling the moisture in raw materials is not enough, environmental factors, including trace moisture in the air, are difficult to control but have a great impact. Organic bismuth is still unsatisfactory, organic tin and amine catalysts that are more sensitive to water are even less applicable. CUCAT series catalysts are developed to meet the bubble free requirements of products in CASE field especially polyurethane elastomer. Different from the common moisture sensitive amine/tin catalysts, it does not catalyze (weakly catalyze) the reaction of trace moisture with isocyanate, so as to avoid generating CO2 bubbles. Under the working conditions of high temperature and high humidity, it can also effectively avoid the result of multi bubbles, cracking, bulging, peeling and lusterless, surface stickiness, etc. Taking CUCAT-DG02 catalyst suitable for MOCA curing as an example, its typical characteristics are very close to organic mercury. https://www.gzyourun.com/polyureth , ane-catalyst/

It is generally recommended for use as an auxiliary catalyst in combination with organic bismuth catalysts. ? Offers excellent compatibility—superior to that of the organic zinc catalyst EZ22. ? Safe and environmentally friendly; solvent-free and odorless.
