ABSTRACT:
Water-dispersible polyisocyanate compositions based on aliphatic and aromatic diisocyanates and having an NCO content, based on solids, of 6 to 21% by weight, a weight ratio of incorporated TDI units to incorporated HDI units of 6:1 to 0.1:1 and a content of ethylene oxide units, arranged within terminal polyether chains, of 5 to 40% by weight; a method for the preparation of these polyisocyanate compositions by reacting a polyisocyanate component with monovalent polyether alcohols containing ethylene oxide units at an NCO/OH equivalent ratio of 2:1 to 120:1; and aqueous coating compositions containing these polyisocyanate compositions and polyhydroxyl compounds as the binder.
