Valikat Polyurethane catalysts
Valikat Polyurethane catalysts Umicore Specialty Materials Brugge (USMB) in Belgium has more than 25 years of experience in the production of catalysts for various applications. We manufacture high quality products under the surveillance of skilled specialists. Our Valikat line of polyurethane catalysts is especially suitable for CASE applications: coatings, adhesives, sealants and elastomeres. The Valikats enable formulators to replace toxic mercury and tin catalysts by sustainable and safe catalysts. Umicore Materials Brugge Umicore Specialty Specialty Materials Brugge NV NV Currently Valikats are being used in: Adhesives Artificial leather Automotive (coatings, interiors, sound dampening materials) Food contact materials Printing Shoe industry Soft-feel materials TPU and many other applications. Under the trade name Valirex, we also produce potassium based trimerization catalysts for the production of PIR foam, and several Zinc based catalysts for producers of flexible foam.

The graph below illustrates typical curing profiles of Valikats compared to mercury and tin based catalysts. However, every PU system behaves in a unique way, and laboratory tests are required to find the most appropriate Valikat version, and the right catalyst load. Under certain conditions Umicore can offer the service of technical advice for the reformulation of catalysts.
