AQUEOUS, HIGHLY CROSS-LINKED TWO-COMPONENT POLYURETHANE COATING SYSTEM, METHOD FOR THE PRODUCTION AND USE THEREOF

摘要

The invention relates to an aqueous, highly cross-linked two-component polyurethane coating system with reduced hydrophilicity and improved resistance to chemicals. The inventive coating system is obtainable by a) producing a binder component on the basis of an aqueous solution or dispersion of low-molecular hydroxy- and/or aminofunctional oligo- or polyurethanes, and b) reacting the binder component a) with a cross-linking component (H) in a ratio of 3:1 to 5:1, the cross-linking component used being water-dispersible polyisocyanate .
