Bismuth belongs to Group 15 in the periodic table of elements. It is the most metallic element in this group and the heaviest stable element in the periodic table of elements. Let’s take a closer look at Organic Bismuth.
Bismuth compounds have green and safe properties such as low cost, easy handling, low toxicity and low radioactivity. In the past 10 years, research on the formation of new organobismuth compounds and on organic composition, catalysts and biomedicine have been carried out. is in a stage of rapid development. Organic bismuth products produced in advanced foreign countries have a history of more than 30 years and have been supplied to the European and American markets for many years. These environmentally friendly organic bismuth catalysts can be cured at room temperature or under heat, making them an excellent choice to replace toxic lead, mercury and tin products.
1. Safe and environmentally friendly, can replace lead, mercury and tin which are being abandoned by legislation;
2. It has very good hydrolysis resistance and stability, reducing The selectivity of reacting with water reduces the side reactions of water and NCO in water-based PU dispersions;
3. Promote NCO/OH reaction, avoid NCO side reactions, and reduce the generation of CO2;

4. In a one-component system, liberate the amine shielded by water instead of promoting the reaction between NCO and water;
5. The combination of bismuth and zinc has a synergistic effect, making the formula and production are more flexible, reduce energy consumption, and increase profits;
6. Can be used alone or in conjunction with amines or other organic metal compounds.
The above is the editor’s introduction to organic bismuth. I hope to be helpful.
