Hardeners for elastic epoxy resin systems, obtained by reaction of (A) reaction products of epoxide compounds (A1) with sterically hindered amines (A3), and/or (B) cyclic carbonates prepared from the compounds (A) and carbon dioxide, and/or (C) cyclic carbonates prepared from reaction products (C1) of epoxide compounds (C11) with polyoxy-alkyleneamines (C13) and carbon dioxide, and, if desired (D) additional epoxide compounds or unreacted residues of the initial epoxides for the preparation of (A), (B) and (C), with (E) polyamines having at least two secondary amino groups, and (F) if desired, further reactants, each of the epoxide compounds (A1) and (C11) containing at least two epoxide groups, and it being possible for monoepoxides to be admixed in each case, if desired. |
