Abstract

Water-dispersible casting mold, especially foundry core, for producing castings,contains a water-insoluble particulate material (I), especially molding sand, and a binder comprising condensed phosphate(s) (II) as first binder component, and polyamine(s) (III) as second binder component. An Independent claim is also included for production of such a mold by mixing (I), (II) and (III) with addition of water, molding and removing (part of) the added free water.
