Cold setting compositions, a process for the production thereof and the use thereof for polyurethane production

Abstract From the Canadian patent

The present invention relates to cold setting compositions of (A) suspensions of solid polyisocyanates with retarded reactivity in aliphatic polyamines and, which are stable under storage due to a polyadduct covering, and (B) polyols and/or water. The activation of the composition is caused by the polyol or water. Additional activating materials can also be added for hardening. Such compositions, which already harden at ambient temperature, are stable under storage have a, long potlife for processing and in relation to the, potlife, have a very short hardening time to the final reaction product.
