  • Patent number: 10189744
    Abstract: Described is the use of a hardening composition for epoxide-amine-based, multicomponent mortar compositions, particularly the use of one of these epoxide-amine-based, multicomponent mortar compositions for chemical fastening purposes. The multicomponent mortar composition contains (A) a resin component, which comprises as a curable compound at least an epoxide resin and optionally at least one reactive diluent, and (B) a hardener component, which comprises a hybrid hardener, wherein the resin component (A) and/or the hardener component (B) optionally comprises other ingredients selected from among inorganic and/or organic compounds. The hybrid hardener is a mixture of (a) at least one amine, selected from among aliphatic, alicyclic, or aromatic amines, as a hardener, and (b) a novolac resin as catalyst, wherein the novolac resin is contained in a quantity of 30 to 45 percent by weight, relative to the total weight of the hybrid hardener.
    Type: Grant
