A WATER-SOLUBLE OR WATER-DISPERSIBLE POLYLSOCYANATE COMPOSITION, A PROCESS FOR ITS PREPARATION AND ITS USE IN COATING COMPOSITIONS

摘要

A water-dispersible polyisocyanate composition obtained by the partial urethanization of the isocyanate groups of 2,4- and/or 2,6-diiso- cyanatotoluene with monohydric and polyhydric alcohols, a process for its production, its use as the binder for an aqueous two-component coating composition in combination with a water-soluble or water-dispersible polyhydroxyl component and coatings for water-resistant sheet-form substrates prepared from this coating composition.
