DBU is a clear, light yellow liquid of relatively low volatility. It has only a slight ammonia-like odor, is miscible with water, and is soluble in most organic solvents has a very strong gellation capability and low odor. It is mainly used in 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, semiflexible.foams, and microcellular systems.

DBU catalysts can be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30 °C. Lower and higher storage temperatures are not preferable and should be avoided.
