Bismuth has emerged as an exceptional catalyst that exhibits Lewis acid properties, simultaneously possessing lower toxicity levels than other metal salts. Bismuth carboxylates serve as an excellent alternative for numerous toxic metal catalysts used in polyurethane systems, thereby enhancing the safety and environmental sustainability of the process.

At TMG-Chemicals, we offer organo-bismuth catalysts that accelerate urethane reactions and improve the final products' properties and performance according to their intended use. These catalysts are non-toxic and highly recommended for PU products that require frequent human interaction.

Organo-bismuth catalysts
*TMG-720 is recommended for 2K PU and block isocyanate coatings.
*TMG-716, 722, 724, and 728 are recommended for PU applications including coating, adhesive, sealant, and elastomer.
*TMG-719 is recommended for PU electrophoretic paint coatings.
*TMG-716 is specifically recommended for PU flooring and PU casting systems.
