Bismuth carboxylates accelerate the reaction between isocyanates and polyols (the urethane reaction) without promotion of any detrimental side-reactions (e.g. water-isocyanate reaction, hydrolysis of esters). As expected, the rate of the urethane catalysis is directly proportional to the concentration of bismuth in the system. We offer a range of bismuth carboxylate catalysts, with varying bismuth concentrations (from 16 wt% – 28 wt%) and varying ligands (2-ethylhexanoic acid, neodecanoic acid).

We offer a range of bismuth carboxylate catalysts, with varying bismuth concentrations (from 16 wt% – 28 wt%) and varying ligands (2-ethylhexanoic acid, neodecanoic acid). Our bismuth carboxylate catalysts are environmentally benign options to industry standard lead, tin, mercury and tertiary amine catalysts.

BiCAT® 8108 (or 8118) is a traditional bismuth carboxylate at 20 wt% (16 wt%) bismuth. This material has been successfully used in one- and two-component systems for ambient or heat cure systems. The lower bismuth concentration gives a less viscous material, allow for easier handling and better flow properties.

BiCAT ® 8 is a polymerization catalyst used in two-component polyurethane systems. Bismuth Catalysts are lower toxicity and serve as highly selective urethane gelling catalysts. They also provide better mechanical properties than other catalysts. Bismuth Catalysts produce a gradual increase in viscosity.

BiCAT ® 8840 is a Bismuth Carboxylate Mixture. It is a liquid ranging in color from yellow to amber, containing 9.5 – 10.5% Bismuth. Shepherd developed the first and only bismuth carboxylates that are truly stable in water.

Bismuth carboxylates are readily soluble in hydrocarbon solvents, including many lubricant base oils (e.g. Group II/III, PAO). Bismuth carboxylates are also effective extreme-pressure (EP) lubricant additives in greases and oils, providing improved lubricity and anti-wear benefits in moving metal parts (e.g. pistons, gears).

Bismuth Neodecanoate is used primarily as a lubricant additive and polyurethane catalyst. It also serves as a non-tin catalyst for RTV silicone applications and for other unique specialty chemical requirements.

Bismuth Nitrate Solution is used in Catalyst Materials and Bismuth Salts.

Bismuth Subcarbonate is used as an opacifier in X-ray diagnostics and can also be used in ceramics, polymer additives, and enamel fluxes. Improves polymer functionality and strength.

Fine-ground white, odorless powder; soluble in Nitric Acid, insoluble in water and alcohol.
