Bismuth naphthenate

Bismuth naphthenate (CAS 85736-59-0), also marketed as Liovac 3016 and sold under the category of naphthenic acids, bismuth salts, is an organometallic compound used industrially as a catalyst.

It delivers bismuth's functional benefits in an oil-soluble form, making it practical for incorporation into liquid formulations across coatings, lubricants, and metalworking fluids.

In coatings and sealants, it functions as a drying catalyst and cure accelerator, replacing lead-based alternatives in alkyd and polyurethane systems for industrial applications.

Metalworking and lubricant formulators incorporate it as an extreme-pressure additive and anti-wear agent in cutting fluids and gear oils to enhance performance under stress.

In the oil and gas sector, it is used in pipeline and downhole fluid formulations where corrosion inhibition under high-temperature conditions is required for equipment longevity.

Automotive lubricant manufacturers also use it to improve film strength and reduce metal-on-metal wear in transmission and engine oil applications for modern vehicle engines.

Bismuth naphthenate is supplied as a viscous liquid or solution, typically in hydrocarbon or naphthenic oil carriers. It is available in technical grade for industrial use.

Bismuth content specifications vary by supplier to suit different formulation loading requirements. Packaging is standard in drums and intermediate bulk containers for industrial volumes.
