    摘要: The present invention relates to a two-component adhesive or sealant composition which consists of a first component K1 and an accelorator component K2. The first component K1 here comprises at least one polyurethane polymer having isocyanatic groups, and the accelorator component K2 comprises at least one salt of a tertiary amine and/or an organic quaternary ammonium salt. These compositions have optional caring characteristics for relatively large adhesive bonds, and more particularly have a sufficiently long open time combined with a rapid strength buildup.

    摘要: The present invention relates to compositions which contain at least one epoxide adduct A having on average more than one epoxide group per molecule, at least one polymer B of the formula (I), at least one thixotropic agent C, based on a urea derivative in a nondiffusing carrier material, and at least one curing agent D for epoxy resins, which is activated by elevated temperature. This composition serves in particular as an adhesive and has an extremely high dynamic resistance to cleavage, in particular at low temperatures.The invention furthermore relates to impact strength modifiers terminated with epoxide groups and of the formula (I). It has been found that these novel impact strength modifiers result in a significant increase in impact strength in epoxy resin compositions, in particular in two-component epoxy resin compositions.
