Umicore offers a premier selection of high-performance accelerators and catalysts for curing unsaturated polyester resins and gelcoats. Under our trusted brands, ECOS and VALIREX, our products are designed to accelerate the decomposition of organic peroxide initiators and enhance cross-linking in polyester resins. With a broad portfolio of metal carboxylates in multiple grades and metal concentrations, Umicore provides tailored solutions to achieve your optimal curing profile.
Ecos cobalt polymer accelerators
Umicore’s innovative ECOS product line introduces a sustainable, low-toxicity curing technology for unsaturated polyester resin and gelcoat applications. Tested rigorously in real-world conditions, ECOS ND15 is a reliable drop-in replacement for traditional unsaturated polymer resin (UPR) cobalt accelerators.
Our cobalt polymer-based accelerators are specifically formulated to mitigate the hazard classifications often associated with standard cobalt carboxylates. Through comprehensive scientific assessment, ECOS ND15 has been classified as a non-hazardous substance, enabling safer usage without compromising quality.
Valirex cobalt neodecanoate accelerators
In addition to our advanced cobalt polymer technology, Umicore continues to provide traditional cobalt-based accelerators through our VALIREX line of metal carboxylates for UPR and gelcoat applications. Our portfolio includes octoate-free options to address toxicity concerns associated with 2-ethylhexanoic acid and its metal salts.
