Catalysts for Polyurethane manufacturing (PU)

Umicore Specialty Materials Brugge (USMB) works with and international team of qualified chemists with more then 25 years experience in different industries.

We synthesize and produce polyurethane catalysts for CASE applications: coatings, adhesives, sealants and elastomers. We developed our Valikat line of tin free and mercury free polyurethane catalysts based on non-toxic bismuth and zinc.

The Valikat products offer advantages such as:

  • Valikat catalysts are non-toxic
  • Valikats can be used as mercury replacement or tin replacement, since mercury and tin catalysts are being phased out due to legislation and hazardous characteristics. This urges manufacturers to find Hg free and Sn free PU catalysts.  As such Valikats are a good alternative to DBTL ( or DBTDL ) and phenyl mercury.
  • Valikat catalysts offer selectivity and can be used as co-catalysts

We invite you to contact us and find your ideal PU Coating, PU elastomer, PU sealant or PU adhesive catalyst.


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.
