Zinc 2-ethylhexanoate

Zinc 2-ethylhexanoate (CAS 136-53-8) is an organozinc carboxylate salt used across coatings, rubber, and polymer industries as a catalyst and curing agent. Its oil-soluble character makes it compatible with organic systems.

In coatings and paint formulations, it functions as a drier and catalyst to accelerate oxidative crosslinking of alkyd resins. This improves through-cure and film hardness in various industrial finishes.

Rubber compounders use it as an activator and crosslinking agent in sulfur-cure and peroxide-cure systems. It is particularly effective where controlled vulcanization rates are required for manufacturing.

In adhesives and sealants, it promotes cure in moisture- or heat-activated systems. This supports bond development in structural and industrial assembly applications across multiple manufacturing sectors.

Polymer producers also employ it as a polymerization catalyst in the synthesis of certain polyesters and polyurethanes. Its chemical stability ensures consistent performance during high-temperature processing.

Zinc 2-ethylhexanoate is supplied as a liquid solution, typically in mineral spirits or other hydrocarbon solvents. The zinc content is specified by weight percentage to meet precise formulation needs.

Standard concentrations vary by application, with coatings-grade material commonly characterized by defined metal content. Technical-grade product is the predominant commercial form for most industrial uses.

Specifications are strictly aligned to industrial end-use requirements to ensure compatibility. This ensures the material meets the necessary performance benchmarks for heavy-duty chemical applications.
