They can be used together with customary epoxy resin curing agents, for example, for the production of adhesives, sealing materials, lacquers or encapsulating resins, and afford products having excellent properties. The epoxysiloxanes according to the invention are also valuable reactive thinners and flexibilizers for curable epoxy resin mixtures.
