DABCO 33LVR A-33 33 33% diethylenediamine dipropylene glycol solution, industrial standard product. The chemical structure of triethylenediamine is unique, as it is a cage like compound with three ethylidenes connected to two nitrogen atoms. The structure of this bimolecule is very dense and symmetrical. From the structural formula, it can be seen that there is no substituent with high steric hindrance on the N atom, and its pair of empty electrons are easily accessible. In the foaming system, once the amino ester bond is formed, it will dissociate, which is conducive to further catalysis. For this reason, although triethylenediamine is not a strong base, it exhibits extremely high catalytic activity for the reaction of isocyanate groups and active hydrogen compounds. It is a strong gel catalyst.
