The invention relates to the use of a curing composition for epoxide amine-based multicomponent mortar compositions, in particular to the use of an epoxide amine-based multicomponent mortar composition containing said curing composition for a chemical fastening process. The multicomponent mortar composition contains (A) a resin component, which comprises at least one epoxide resin as a curable compound and optionally at least one reactive diluent, and (B) a curing component, which comprises a hybrid curing agent. The resin component (A) and/or the curing component (B) optionally comprise additional components selected from inorganic and/or organic compounds. The hybrid curing agent is a mixture of (a) at least one amine, selected from aliphatic, alicyclic, or aromatic amines, as a curing agent and (b) a novolac resin as an accelerator, said novolac resin being present in a quantity ranging from 30 to 45 wt.%, based on the total weight of the hybrid curing agent. The use of the hybrid curing agent leads to a rapid curing of the multicomponent mortar composition even at low temperatures when completely curing the mortar composition. In this manner, high load values of the cured mortar composition at low temperatures (+5 °C) as well as at high temperatures (+50 °C) and an improved creep resistance at high temperatures (+50 °C) are achieved. Additionally, the use of free phenols can be completely omitted. |
