K-18218/A Adducts of hydroxyl group containing epoxy resins and isocyanates and use thereof Adducts obtainable by reacting (a) an epoxy resin having a OH value of 0.02-1.5 equivalents/kg and (b) a di- or polyisocyanate, said reaction being carried out with exclusion of moisture and essentially without a catalyst, can subsequently be converted by reaction with an inhibitor (c), preferably an acrylate, into storage-stable adducts. The adducts can be cured in the presence of a latent hardener conventionally used for EP/IC resin systems in a weakly exothermic reaction to give crosslinked products which have excellent properties.
