Abstract
Discussed are heat-curable epoxy resin compositions containing at least one epoxy resin A with, on average, more than one epoxide group per molecule, at least one curing agent B for epoxy resins, which is activated by an increased temperature, at least one terminally blocked polyurethane prepolymer of formula (I) and at least one epoxide-terminated polyurethane prepolymer of formula (II). The epoxy resin compositions are particularly suitable for use as one-component, heat-curable adhesives and are characterized by excellent mechanical properties, high glass transition temperatures and high impact resistance.
