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.
