    Abstract: 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 polyoxyalkyleneamines (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.

    Abstract: An elastically-cured epoxy resin composition is disclosed that contains compounds that contain at least two 1,2-epoxide groups. The epoxide groupcontaining compounds are reaction products of compounds (A1) that contain at least two 1,2-epoxide groups per molecule, polyoxyalkylenemonoamines (A2) that have a molecular weight (number average) greater than 900 g/mol, and optionally polycarboxylic acids (A3). The polyoxyalkylenemonoamines (A2) are polyoxypropylenemonoamines which preferably contain a mole fraction of up to 20% of oxyethylene units based on the total amount of oxypropylene and oxyethylene units. The resin composition additionally contains at least one hardener (B) and, if desired, customary additives (C).

    Abstract: Curing agents for epoxy resins comprising products of the reaction of (A) polyamidoamines obtained by polycondensation of (a) dicarboxylic acids containing oxyalkylene groups, or derivatives thereof, with (b) polyamines containing at least two amino groups which are capable of condensation with (a), (B) polyamines containing at least two secondary amino groups and (C) adducts of (c) polyepoxide compounds and (d) polyalkylene polyether polyols. Epoxy resins cured by means of these curing agents exhibits, in particular, very good water resistance.
