Polycat® DBU

Technical Datasheet | Supplied by Evonik
DiazoBicycloUndecene. Polycat® DBU Catalyst, being a tertiary amine, is a polyurethane additive that promotes the urethane (polyolisocyanate) reaction in coatings and CASE applications. It displays very strong gelation capability, imparts low odor and is used in formulations containing aliphatic isocyanates as they require exceptionally strong catalysts because they are much less active than aromatic isocyanates. The optimum storage temperature is between 10°C and 30°C.
