Abstract:
The present invention relates to a pultrusion resin system, comprising (a) di- or polyisocyanates, (b) compounds having at least two groups reactive toward isocyanates, (c) catalyst, (d) polybasic acid with functionality greater than or equal to 2 and, optionally, (e) further auxiliaries and additives, where the boiling point of the polybasic acid is at least 200° C. at standard pressure and it is soluble in the compound having at least two groups reactive toward isocyanates. The invention further relates to a process for producing a pultrudate, and also to this pultrudate.
