Polyurethane is an important polymer material, which is widely used in coatings, adhesives, sealants, elastomers, foam materials and other fields. Catalysts play a crucial role in the synthesis of polyurethane.
PU catalyst is an auxiliary agent used to accelerate the reaction of isocyanate groups (NCO groups) with hydroxyl groups(OH groups） or water. Common catalysts in the polyurethane industry include amine catalysts and metal catalysts, among which amine catalysts are mostly used in PU foaming systems, and the finished products include various polyurethane rigid and flexible foam products; Metal catalysts are mostly used in polyurethane gel systems, and the finished products include PU coatings, PU adhesives, PU sealants and PU elastomers.
The common catalysts currently used in the polyurethane industry, such as organic mercury, organotin, organolead, etc., all contain varying degrees of toxicity and are harmful to the environment and human health. With the development of society, human demands for environmental protection are becoming increasingly high, and the polyurethane industry is also calling for eco-friendly catalysts that are harmless to the environment and human health.
The eco-friendly PU catalyst aims to promote the polyurethane generation reaction while reducing the negative impact on the environment. Eco-friendly PU catalysts typically do not contain harmful heavy metal elements such as mercury, tin, and lead, and require no increase in volatile organic compound (VOC) emissions. Among them, bio based catalysts can degrade in natural environments, reducing environmental pollution and are an ideal eco-friendly catalyst.
Guangzhou Yourun has been dedicated to the research and production of eco-friendly PU catalysts for many years, and has launched multiple series of eco-friendly PU catalysts in the industry, including:
The BCAT and ZCAT series of universal bismuth zinc catalysts, such as BCAT-E16 and BCAT-E20, are comparable to internationally renowned brands;
The eco-friendly bubble-free catalyst CUCAT series, such as CUCAT-HAB, meets the bubble-free requirements of PU products without affecting their transparency;
The AUCAT series of eco-friendly hydrolysis resistant catalysts, such as AUCAT-AS11, improve the storage stability of catalysts in aqueous formulations and are widely used in the PU adhesive industry;
The WCAT series of eco-friendly moisture curing catalysts, such as WCAT-WH03, are widely used in one-part moisture curing systems with high environmental requirements, such as sealants, hot melt adhesives, etc.
Eco-friendly low VOC catalysts, such as the CUCAT-V series, are widely used in the runway and floor coating industries to meet the stringent low VOC emission requirements of the sport track and floor coating industries.
Green environmental protection is the theme of today's social and environmental development, and it is also the direction of the future development of the polyurethane industry. Guangzhou Yourun will continue to focus on the development of environmentally friendly polyurethane catalysts and strive to solve the pain points of the polyurethane industry.
