Function and use
Safety instructions: S23; S24/25 bismuth neodecanoate is used as a catalyst in the polyurethane industry, showing high catalytic activity, widely used in spraying, high-density elastomers, and microporous elastomer systems.
Has the following characteristics:
Bismuth neodecanoate is a powerful gel catalyst, which promotes the completion of the reaction later
It shows the delayed system viscosity when the level of intermolecular reaction is low at the beginning of the reaction;
Environmentally friendly products that can replace catalysts containing lead and tin;
In ordinary polyurethane reaction systems, microporous elastomer systems and high-density semi-rigid foam systems enhance the stability of system reactions.

Features and uses:
MB20 is used as a catalyst in the polyurethane industry, showing high catalytic activity, and is widely applicable to spray, high density elastomer, and microcellular elastomer systems. Has the following characteristics:
A powerful gel catalyst to promote the completion of the reaction in the later stage;
It shows that the viscosity of the system is delayed when the level of intermolecular reaction is low in the early stage of the reaction;
Environmentally friendly products that can replace lead and tin-containing catalysts;
In the common polyurethane reaction system, the microcellular elastomer system and the high-density semi-rigid foam system enhance the stability of the system reaction.
Acts as a co-catalyst with a tertiary amine to accelerate the urethane reaction and cure. Exhibits delayed viscosity build on front-end at low usage level while promoting excellent back-end cure. It is free of mercury, lead and dibutyl tin. Possesses low volatility with little or no odor. It has compatibility with common rigid and flexible foam polyols.
It is an alternative to tin-based catalysts in flexible slabstock, high-density flexible foams, spray, microcellular, and rigid foam systems.
Recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use.
