    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.

    摘要翻译： 本公开内容涉及冲击强度改性剂，其衍生产物及其在制备双组分环氧树脂组合物中的用途。 本公开特别涉及通过使具有异氰酸酯基团的聚氨酯预聚物，伯二胺和任选的至少一种迈克尔受体反应制备的氨基封端的冲击强度改性剂。 由此配制的双组分环氧树脂组合物的特征在于在保持可接受的拉伸剪切强度的同时大大增加冲击强度。 根据本公开的冲击强度改性剂和包含其的环氧树脂组合物特别适用于车辆制造。

    摘要： The present invention relates to a two-component epoxy adhesive composition comprising a) a first component comprising a first epoxy resin and a second epoxy resin, the second epoxy resin being flexibilized by an elastomer, and b) a second component comprising at least one amine compound with one or more primary and/or secondary amino groups, said amine compound having a molecular weight of less than 450 g/mol. The ratio of the total number of amino groups of the amine compound to the total number of epoxy groups of the epoxy resins is 0.01:1 to 0.5:1. The mixing of the two components a) and b) results in a wash-off resistant composition. Said wash-off resistant composition results upon heat-curing in a crash-stable structural adhesive.
