Application
Use AminCat DBU catalyst mainly for specialized applications that require very strong catalysis. These applications include formulations containing alicyclic or aliphatic isocyanates, which are much less active than aromatic isocyanates and therefore require exceptionally strong catalysts. The product is recommended for evaluation in integral skin semi-flexible foams and microcellular systems.
Packaging
Available packaging: 200 KG steel drums.
Special packaging is available on request.
Storage
Store 1,8-Diazabicyclo[5.4.0]undec-7-ene in a cool, dry, and well-ventilated area, ensuring compliance with legal requirements. Additionally, keep AminCat DBU away from heat sources and oxidizing agents to maintain safety and effectiveness.
