A trimerization catalyst composition comprising a trimerization catalyst compound selected from one or more organic metal salt, preferably alkali or earth alkali metal salts, and one or more compounds selected from compounds which comprise a carboxamide group having the structure -CO-NH 2 and/or from compounds which comprise a group having the structure -CO-NH-CO- is disclosed. n Further a stable polyisocyanate composition comprising the catalyst composition and a process for making the polyisocyanate composition is disclosed. n A curable polyisocyanate composition is obtained comprising the catalyst composition, a polyisocyanate composition, an epoxy resin and optionally a polyol/monool composition and a polyisocyanurate comprising material made by allowing the curable composition to react at elevated temperature and a process for making the polyisocyanurate comprising material. |
