Typical characteristics of organic bismuth catalysts:
1. Safe and environmentally friendly, it can replace organic lead, mercury and tin in some applications;
2. Better hydrolysis resistance than T9;
3. Promote the NCO/OH reaction. In oily or waterborne polyurethanes, the side reaction of water and NCO groups can be reduced to some extent, and the formation of CO2 can be reduced.
Organic bismuth catalysts has good compatibility and can be used alone or in combination with other organometallic compounds.
Organic bismuth catalysts is used in all areas of the polyurethane industry, such as elastomers, coatings, foams, sealants, PU synthetic leather, shoe materials, runways and more.
