Cucat Series Of Bubble Free Catalyst - China

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.
