Claim Text:
1. A curable composition for making a polyisocyanurate material by allowing the curable composition to react at elevated temperature above 50° C. comprising: a polyisocyanate composition comprising a compound comprising a group having the structure —CO—NH—CO— in such an amount that the ratio of the number of —CO—NH—CO— groups to the number of isocyanate groups is at most 1, and a lithium halide, and a urea compound, having an average molecular weight of 500-15000 and optionally comprising biuret groups, and an epoxy resin, wherein the number of moles of lithium halide per isocyanate equivalent ranges from 0.0001-0.04 and the number of urea+biuret equivalents per isocyanate equivalent ranges from 0.0001-0.4 and the number of epoxy equivalents per isocyanate equivalent ranges from 0.003-1; and wherein the curable composition is stable up to 40° C.
