Abstract

The present invention relates to a method for reducing the ionic strength or certain polyvalent ions in aqueous dispersions of organic binding agents or inorganic solid bodies by means of electrodialysis and a cell package (100) which is suitable for the method according to the invention. The method according to the invention permits aqueous compositions of the dispersed components to be stabilised by regulating the ionic strength or the concentration of certain polyvalent ions and hence significantly increase the durability and throughput times of coating baths for example. More particularly the process is used in the removal of polyvalent metal cations from anionically stabilised aqueous binding agent dispersions. A special application exists in removing from autophoretic baths which contain anionically dispersed organic binding agents and possibly inorganic pigments for forming protective layers on metallic components polyvalent cations of zinc iron and aluminium which accumulate in the bath due to pickling processes when a number of components the surfaces of which are produced at least partially from zinc iron and/or aluminium are passed through.
