Zinc 2-ethylhexanoate

Zinc 2-ethylhexanoate (CAS 85203-81-2) is an organozinc carboxylate salt used as a catalyst, curing agent, and metal coordination component in polymer processing, coatings, and rubber manufacturing.

Where is Zinc 2-ethylhexanoate used?

• PVC and polyurethane processing: catalyst and stabilizer precursor
• Rubber and elastomer manufacturing: curing co-agent that promotes vulcanization efficiency
• Coatings and alkyd resin systems: drier or catalyst that accelerates oxidative crosslinking and film formation
• Lubricants: metal-containing additive that improves load-bearing performance
• In metalworking fluids it helps reduce surface wear.

Good to know: Its solubility in organic media makes it practical for liquid-phase formulation work where inorganic zinc sources are unsuitable.

Commercial specifications

• Liquid or viscous solution, typically in hydrocarbon or mineral spirit carriers
• Defined zinc content concentrations
• Zinc assay specifications commonly used as the primary quality parameter for procurement
• Bulk quantities in drums and IBCs
