The present invention relates to polyisocyanurate systems, to pultrusion of these systems for producing reinforced polyisocyanurate matrix composites, and to composites produced thereby. The polyisocyanurate system comprises a polyol component, optional chain extender chain extender cyanate. The polyisocyanurate system has an extended onset time of about 5 minutes to about 30 minutes at room temperature and can be snap cure. |
