Zusammenfassung:	The present application provides agents for producing an impact-modified epoxy adhesive encompassing at least two components A and B packaged separately from each other, wherein (a) component A contains at least one compound having two or more isocyanate groups together with one or more further additives, (b) component B contains at least one compound which has at least two reactive groups selected from hydroxyl groups, thiol groups, primary amino groups and secondary amino groups and is simultaneously free from epoxy groups, together with one or more further additives, (c) at least one of components A and/or B contains at least one epoxide prepolymer as an additive, (d) at least one of components A and/or B contains at least one latent hardener for epoxide prepolymers as an additive, and (e) components A and B contain no blowing agent that is capable of being heat activated.
