Imidazole derivatives as accelerators for curing process of isocyanate-epoxy compositions
1-Me and 1-Et imidazoles were added (0.5 to 2.0 parts per 100 parts) to a mixt. of epoxy resin and trimethylhexamethylene diisocyanate (1:2 mole ratio) to accelerate the curing. The addn. resulted in a decreasing the temp. of exothermic effect and gel point of the mixt.
