Bismuth naphthenate

Bismuth naphthenate (CAS 85736-59-0), also marketed as Liovac 3016, is an organometallic compound used industrially as a catalyst.

Where is Bismuth naphthenate used?

• Coatings and sealants: drying catalyst and cure accelerator replacing lead-based alternatives in alkyd and polyurethane systems
• Metalworking and lubricants: extreme-pressure additive and anti-wear agent in cutting fluids and gear oils
• Oil and gas: corrosion inhibition in pipeline and downhole fluids under high-temperature conditions
• Automotive lubricants: improves film strength and reduces metal-on-metal wear in transmission and engine oils
• It delivers bismuth's benefits in an oil-soluble form for liquid formulations.

Commercial specifications

• Viscous liquid or solution in hydrocarbon or naphthenic oil carriers
• Bismuth content varies by supplier
• Drums and intermediate bulk containers
