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 polyureth , ane 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.

Yourun is one of the companies that produce the largest variety of organic bismuth catalyst in the world. Besides the general purpose bismuth catalyst, You run also supplies bismuth catalyst for specific purposes, such as TPU, polyester, low VOC, reactive organic bismuth, etc. Yourun Organic Bismuth Catalysts are divided into conventional type and innovation type, which have different application fields. General features of organic bismuth catalyst: Environmental protection: meet the requirements of international environmental protection regulations Promote NCO / OH reaction, reduce the side reaction between water and - NCO and reduce the generation of CO2 compared with organic tin catalyst; However, the selectivity of reducing the reaction between isocyanate and water is not as good as CUCAT series catalysts. The catalytic activity is quite high, but lower than that of organic tin catalyst. It is easy to hydrolyze and inactivate in water, but it is more stable than T- 9; For hydrolysis resistant and eco-friendly catalysts, please select AUCAT series. It will affect transparency when used in polyester system. AUCAT series is recommended for polyester system. The flowable time is short in the early stage and the strength increases slowly in the later stage. Classification of organic bismuth catalysts: it is subdivided into five sub series of BCAT, BCAT-A,BCAT-B, BCAT-C and BCAT-T, with dozens of models.Yourun is one of the companies that produce the largest variety of organic bismuth catalyst in the world. In addition to products that have no difference with imported brands of organic bismuth, it also provides products for special or specific purposes, such as TPU, polyester, low VOC, reactive organic bismuth, etc.

Chemical Raw Material for Spray Urethane and Spray Urea, Yourun's products include: Polyurethane/Polyurea Catalysts Defoamer (Defoaming Agent) Rheological Agent Anti-abrasion Agent (Anti-wearing Agent) Antistatic Agent. Main Advantages of the Spray Urethane and Spray Urea: Two component spray polyurethane/urea chain extender components contains polyol (usually PPG) which has the similar reaction rate with MDI as that of H2O. If catalysts such as organic bismuth tin, which have a strong catalytic effect on water (sensitive to moisture), are selected, even if the raw materials are completely dehydrated, it cannot avoid adverse phenomena such as foaming, bulging, peeling, and cracking caused by the reaction of trace moisture with isocyanates to produce CO2 when constructs on high-temperature summer and humid substrates. CUCAT-HA02 has unique targeted catalytic properties and extremely high catalytic activity that do not catalyze the reaction of trace moisture with isocyanates. It is used for spraying polyurethane/urea coatings and has the following prominent characteristics: The gel is dense and has higher strength without bubbles. Generally, the strength is increased by 10 to 30% compared to using tin bismuth catalysts. Improve the undesirable phenomenon of hollowing and peeling, and improve the adhesion fastness between the coating and the base surface. It greatly reduce the influence of wet substrate and water vapor on the coating under high temperature and high humidity conditions, and avoid the problem of hollowing and peeling caused by gas accumulation at the bonding interface caused by the use of organic bismuth catalyst. The formula is flexible in material selection to further reduce the cost. Minimize the use of expensive amine terminated polyether and aromatic amine (DETDA / E100). Allow more PPG to be used in the formula, even allow the use of low activity diamines such as MOCA to replace DETDA as component P, and there will be no adverse phenomena such as foaming and bulging. While the use of ordinary bismuth catalyst to reduce the amount of DETDA or MOCA is very easy to foaming and bulging. High catalytic activity, low usage, fast increase in viscosity and initial strength.
