Product Applications
  • POLYCAT® DBU is mainly used for specialized applications requiring very strong catalysis. These applications include formulations containing alicyclic or aliphatic isocyanates, which are much less active than aromatic isocyanates and require exceptionally strong catalysts.
  • The product is recommended for evaluation in integral skin semi-flexible foams and microcellular systems.
  • POLYCAT® DBU can be used as a highly active urethane promoting catalyst in microcellular and CASE applications.
