VERFAHREN ZUR HERSTELLUNG VON FEUCHTIGKEITSHAERTENDEN BINDEMITTELKOMBINATIONEN, DIE NACH DIESEM VERFAHREN ERHAELTLICHEN KOMBINATIONEN UND IHRE VERWENDUNG

A process for preparing moisture-curable binder compositions by mixing and if necessary reacting, in the absence of moisture, A) compounds which contain at least two intramolecular carboxylic anhydride groups with B) organic compounds having blocked amino groups, at least some of which consist of hexahydropyrimidinyl or tetrahydroimidazolyl groups, the type and ratio of components A) and B) being chosen, taking into account any addition reaction which takes place spontaneously in the absence of moisture between the components A) and B), so that there are 0.25 to 50 anhydride groups per hexahydropyrimidinyl or tetrahydroimidazolyl group in the resulting composition; the binder compositions obtainable by this process and their use as surface coatings or coating materials curable under the influence of moisture or for the production of such surface coatings or coating materials.
