PECULIER TWO-PACK POLYURETHANE-BASE WATER-BASE PAINT COMPOSITION AND ITS PRAPARATION

摘要

A two-component coating composition which optionally contains the conventional auxiliaries and additives and contains, as binder components, a) a polyol component comprising at least one hydroxyl-containing polymer of olefinically unsaturated compounds and b) a polyisocyanate component having a viscosity of from 50 to 10,000 mPa.s at 23 DEG C, comprising at least one organic polyisocyanate in amounts corresponding to an NCO/OH equivalent ratio of from 0.5:1 to 5:1, is characterised in that component a) is an aqueous solution and/or dispersion of a hydroxyl-containing polymer in which the polyisocyanate component b) is present in emulsified form.
