    摘要： The disclosure relates to the field of two-component epoxy resin compositions and to the use thereof as a repair adhesive, in particular in vehicle manufacturing. The two-component epoxy resin compositions according to the disclosure contain a curing component K2, which comprises between 1 and 10 wt. % of an amino group-terminated polyamide B, together with an epoxy resin component K1. The compositions show that the impact resistance is highly increased while an acceptable sheer strength is simultaneously retained.

    摘要： The present disclosure relates to impact strength modifiers, the derivative products thereof, and the use thereof in producing two-component epoxy resin compositions. The disclosure in particular relates to amino group terminated impact strength modifiers prepared by reacting a polyurethane prepolymer having isocyanate groups, a primary diamine, and optionally at least one Michael acceptor. The two-component epoxy resin compositions thus formulated are characterized by a great increase in impact strength while retaining an acceptable tensile shear strength. The impact strength modifiers according to the disclosure and the epoxy resin compositions comprising same are in particular suitable for vehicle manufacturing.

    摘要： Discussed are heat-curable epoxy resin compositions containing at least one epoxy resin with, on average, more than one epoxide group per molecule, at least one curing agent for epoxy resins, which is activated by an increased temperature and at least one terminally blocked polyurethane prepolymer. Said 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.
