Htzn1: 19% Htzn2: 23% 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 metas 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 customersâ??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.

Organic bismuth catalysts Product Bi-16 Bi-20 Bi-28 Performance 1. Selective polyurethane gel catalysts; 2. Compared with tin catalysts, it has better selectivity to nco, and end productsmechanical performance is better; 3. Induction time is short, viscosity increases gradually. Advantages of organic bismuth polyurethane catalysts 1. Safe & environmentally-friendly catalysts, can replace plumbum(pb) & mercury(hg) catalysts and tin catalysts which are being abolished by legislation; 2. Bi catalysts have a better stability to hydrolysis resistance than tin catalysts, reduce reaction selectivity with water, reduce sidereactions of nco group and water reaction in water-borne pu dispersing agent; 3. Promote the reaction of nco/oh , avoid sidereactions of nco and reduce co2 form; 4. In one-component system, emancipate the amine shielded by water, rather than promote the reaction of water and nco; 5. Combination of bismuth & zinc has synergy effect, making formulation and production more flexible, reducing energy consumption and increasing profits; 6. Can be used alone, or used together with amine or other organic metal compounds as auxiliary catalyst.
