The global cerium octoate market was valued at USD 65 million in 2024 and is projected to reach USD 96 million by 2032, at a CAGR of 5.0% over the forecast period, according to 24ChemicalResearch. Cerium octoate (cerium 2-ethylhexanoate) is a rare-earth metal carboxylate widely used as an oxidation catalyst, paint drier and adhesion promoter in coatings, inks, resins and polymer systems.

Cerium octoate is the most effective replacement for lead-based paint driers, accelerating the autoxidation and through-drying of solvent- and water-borne alkyd and epoxy coatings and inks, and improving hardness, gloss and film durability while enabling lead-free coating formulations. It also functions as an oxidation catalyst and stabilizer in polyester, unsaturated resin and specialty polymer systems, and is used in exhaust and catalytic applications. Demand is tied to the global shift toward lead-free driers, the expansion of industrial and architectural coatings, and the growing use of rare-earth metal carboxylates in high-performance formulations.

Asia-Pacific is the fastest-growing region, supported by expanding coatings, inks and resin industries in China, India and Southeast Asia, with Europe and North America sustaining demand for high-performance, lead-free driers and catalysts. Continued coatings growth and the phase-out of lead-based driers position cerium octoate as a resilient, structurally advancing rare-earth metal carboxylate product.
