Product Description
| Product Name: | organic zinc |  |
| Performance: | 1. ZN content: 19%. 2. Compared with bismuth and zinc catalysts, the reaction rate is slow. 3. Very effective crosslinking catalyst, the surface of the final product is not sticky. | |
Application:
| The use of bismuth zinc composite catalyst, instead of mercury catalyst, zinc to strengthen the post-curing, in order to achieve the gel.We have developed a bimetallic bismuth-zinc composite catalyst for the regulation of the state or the requirement of some customers to replace the mercury catalyst. In this kind of catalyst, bismuth provides the gel speed required for curing, high selectivity to produce polyurethane at a high rate, and zinc acts as a slower gel and a better cross-linking catalyst, which can reduce the acidity of the system and accelerate the cross-linking after the reaction. The user can adjust the gel behavior by changing the concentration of these two metals in the system. For example, by adding organic zinc to increase the zinc in the system, the operation time in the kettle during the induction period is prolonged, and the post-curing is promoted. Due to the different reaction systems of the users, bismuth and zinc are not the same. Keep the amount of bismuth unchanged, by adding different amounts of zinc to test, control the ratio of bismuth to zinc between 1:1-1:10, find out the ratio of bismuth to zinc suitable for their own system. | |
