Organic zinc catalysts
Performance 1. Compared with Bismuth and zinc catalysts, reaction speed is slow; 2. Very effective crosslinked catalyst, surface of end products does not stick hand. Use Bi-Zn composite catalysts to replace mercury catalysts and add Zn to strengthen post curing To satisfy requirements of adjusting Gelling State or replacing mercury catalysts, we developed a dual metal Bi-Zn composite catalyst. In this kind of catalyst, Bismuth provides gelling speed for curing to form polyurethane electively and rapidly; Zinc as slower gelling and better crosslinked catalyst can reduce system acidity and promote crosslinking after accelerate reaction .
Users can adjust the Gelling state by changing the two metal’s concentration in this system. Such as, by adding HTZN1 (19% zinc) or HTZN2 (23% zinc) to increase the zinc content in system, then to extend the operation time in Reactor in induction period and promote post cure. Because the customers’reaction systems are different, the best rate of Bismuth and Zinc is also different. Remain Bismuth unchanged , by adding different amount of zinc to test, control rate of Bismuth and Zinc between 1:1 to 1:10 proportion, to find out the rate of Bismuth and Zinc which is most suitable for own systems.
With excellent management and development advantages, advanced development concept, advanced development idea and successful operation mode, the products of Industrial Grade High Purity Polyester Resin Raw Material Ethylene Glycol/Meg/107-21-1 are welcomed all over the world. We usually concertrating on acquiring new creative products to fulfill request from our clientele all around the world. Over the years, we have continued to innovate and surpass ourselves, always firmly believe that 'development is the last word', build brand with quality, and improve brand with service. We are striding forward to a first-class enterprise with a pioneering and innovative spirit.
