ABSTRACT:
Epoxy resin compositions containing polyepoxides having at least two 1,2-epoxide groups are disclosed. The polyepoxides can be obtained by reacting (i) di- or polyepoxides or mixtures thereof with monoepoxides, (ii) one or more amines chosen from sterically hindered amines, disecondary diamines and diprimary diamines to form an epoxide-amine adduct, and (iii) subsequently reacting the epoxide-amine adduct with polyfunctional isocyanates. The composition also contains curing agents for the polyepoxides and can optionally contain additional 1,2-epoxide compounds and additives. The compositions are useful as coatings for bridging cracks, as adhesives and as constituents of paints.
