Binders for aqueous corrosion protection systems, comprising products A′ABC of reaction of epoxy resins, fatty acids, and amines, having a number average molar mass Mn of at least 5000 g/mol, obtained by reacting epoxide compounds A′ containing at least two epoxide groups per molecule and reaction products ABC of epoxide compounds A, fatty acids B, and amines C, wherein, where appropriate, the epoxide compounds A′ and/or the epoxide compounds A have been modified prior to further reaction, in whole or in part, by reaction with compounds D containing at least one acid group or hydroxyl group reactive toward epoxide groups, and wherein, where appropriate, the amines C have been modified prior to further reaction, in whole or in part, by reaction with aliphatic or aromatic monoepoxide compounds A″ or mixtures thereof.
A product A′ABC of reaction of epoxy resins, fatty acids, and amines, wherein it is a reaction product of epoxide compounds A′ containing at least two epoxide groups per molecule and reaction products ABC of epoxide compounds A containing at least two epoxide groups per molecule, fatty acids B, and aliphatic amines C having from 2 to 12 carbon atoms, and wherein its number average molar mass Mn is at least 5 000 g/mol, and, the epoxide compounds A′ and/or the epoxide compounds A optionally having been modified prior to further reaction, in whole or in part, by reaction with compounds D containing at least one acid group or hydroxyl group reactive toward epoxide groups, and, the amines C optionally having been modified prior to further reaction, in whole or in part, by reaction with aliphatic or aromatic monoepoxide compounds A″ or mixtures thereof.
