What is Zinc 2-ethylhexanoate?
Zinc 2-ethylhexanoate (CAS 136-53-8) is an organozinc carboxylate salt used as a catalyst and curing agent in coatings, rubber and polymer industries.
Where is Zinc 2-ethylhexanoate used?
- Coatings and paint: drier and catalyst accelerating oxidative crosslinking of alkyd resins, improving through-cure and film hardness
- Rubber: activator and crosslinking agent in sulfur-cure and peroxide-cure systems, effective where controlled vulcanization rates are needed
- Adhesives and sealants: cure promoter in moisture- or heat-activated systems, supporting bond development in structural and industrial assembly
- Polymer production: polymerization catalyst in the synthesis of certain polyesters and polyurethanes
- Its oil-soluble character makes it compatible with organic systems.
Commercial specifications
- Liquid solution, typically in mineral spirits or other hydrocarbon solvents
- Zinc content specified by weight percentage
- Standard concentrations vary by application; coatings-grade material characterized by defined metal content
