Cerium 2-ethylhexanoate

Cerium 2-ethylhexanoate (CAS 24593-34-8), also known as cerium(III) tris(2-ethylhexanoate), is an organocerium salt used industrially as a catalyst and curing agent.

Where is Cerium 2-ethylhexanoate used?

• Coatings: drier and oxidative cure promoter, accelerating cross-linking in alkyd and air-drying resin systems
• Polymers: polymerization catalyst and co-catalyst, particularly where rare earth metal activation is needed
• Lubricants and metalworking fluids: additive precursor where controlled metal content supports performance at elevated temperatures and pressures
• Sealants and elastomers: promotes cross-linking and improves cure response in specialty rubber compounds
• It delivers cerium in an oil-soluble, organically compatible form for coating, polymer, and lubricant systems where inorganic cerium salts would be incompatible.

Commercial specifications

• Liquid solution, typically in hydrocarbon or mineral spirit carriers
• Cerium metal content expressed as a percentage by weight
• Standard concentrations range from 6% to 12% cerium by weight
• Technical-grade material is the primary specification, with purity confirmed by ICP analysis per buyer requirements
