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.
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.
