ABSTRACT:
A cold hardening binding agent for binding particulate solid materials is based on a mixture of a polyhydroxy compound and a polyisocyanate, and the polyhydroxy compound consists at least in part of a nitrogen basic polyol. The nitrogen basic polyol accelerates reaction and hardening time. An alkali or alkaline earth metal acetate or formate may also be employed to accelerate hardening.
