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 Octoate 8.2% is a versatile compound used as a paint drier, a lubricant additive, and a polyurethane catalyst.

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.
