    Abstract: An elasticized addition product formed from (a) polyalkylene ether-polyols having a molecular weight of 500 to 10,000 and 2 to 6 C atoms in the alkylene radical and (b) polyisocyanates, the ratio of the NCO groups of the component (b) to the OH groups of the component (a) being 1.5:1 to 2.5:1, and the addition product of (a) with (b) is further reacted with hydroxyl compounds from the group comprising (c) imidazolidine of a particular formula and/or (d) hexahydropyrimidine derivatives of a particular formula in an approximately 1:1 ratio of NCO groups to the OH groups of the components (c) and/or (d), and is in the form of this reaction product and/or in the form of a hydrolysis product thereof. Mixtures based on (A) the said addition product as the curing agent and (B) epoxide compounds containing more than one epoxide group, if appropriate together with monoepoxide compounds, are used for the production of molded articles having controlled resilience properties, such as sheet-like structures, adhesive bonds and casting compositions.

    Abstract: Heat hardenable binders comprising aqueous dispersions of solid epoxy resins of a special structure, wherein some of the glycidyl groups are converted into quaternary ammonium groups by means of primary and/or secondary amines and quaternization, and further containing hardeners and possibly other conventional additives, characterized in that they contain, as hardeners, polybasic water-soluble polycarboxylic acid units or the anhydrides or acid esters thereof having a COOH functionality of at least 3, and the use of the binders for the preparation of hardened products, particularly coatings.
