With expertise in metal carboxylate manufacturing, Umicore has an extensive portfolio of polyurethane (PU) catalysts and isocyanate blockers tailored to diverse applications. Our specialty chemicals are integral to a wide range of polyurethane solutions, including coatings, adhesives, sealants and elastomers (PU CASE) and rigid and flexible foam. Umicore’s solutions provide precise control over reaction profiles and processing times. Â
Umicore’s PU CASE product range includes two core segments: isocyanate blockers, which enhance stability and processing flexibility, and metal-based PU catalysts that vary in bismuth and zinc content for customizable reaction profiles. Adjusting these elements enables precise fine-tuning of polyol-isocyanate reactions, helping achieve ideal properties like hardness, flexibility, and durability, essential to each formulation’s performance.
