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.

Abstract: A process for the preparation of aqueous epoxy resin dispersions comprising (1) 20 to 75% by weight, based on the total dispersion, of an epoxy resin constituting a condensation product of a) epoxy compounds having at least one epoxy group per molecule and an epoxide equivalent weight of 90 to 3000 g/mol, and b) aromatic polyols; (2) 3 to 20% by weight, based on the total dispersion, of an emulsifier comprising a) a condensation product of an aliphatic polyol and an epoxy compound having at least two epoxy groups per molecule and an epoxide equivalent weight of 90 to 3000 g/mol, the equivalent ratio of the OH groups to the epoxy groups being 1:0.85 to 1:1.5 and the epoxide equivalent weight of this condensation product being between 5000 and 400,000 g/mol, b) an organic solvent, and c) water; (3) up to 10% by weight, based on the total dispersion, of organic solvents; and (4) water in an amount to make up to 100% by weight, which comprises stirring the epoxy resin (1) firstly with the emulsifier (2) and, if appropriate, organic solvents corresponding to (3), and then with water.

Abstract: Curable, pulverulent mixtures of A) carboxyl-containing polyesters, B) compounds which contain at least two 1,2-epoxide groups and are products of the reaction of B1) compounds containing at least two 1,2-epoxide groups per molecule and having epoxide equivalent weights of from 160 to 600 and B2) aromatic dicarboxylic acids or mixtures thereof with compounds from the group comprising (cyclo)aliphatic dicarboxylic acids, monocarboxylic acids and/or monohydric phenols, and B3) optionally cyclic anhydrides, and C) optionally conventional additives, are distinguished, in particular, by improved yellowing resistance and/or increased reactivity.
