The present invention relates to solvent-free two-component polyurethane coating compositions containing A) a polyisocyanate component having a viscosity at 23°C of 500 to 12,000 mPa.cndot.s, an isocyanate content of 13 to 24% by weight and a content of monomeric diisocyanates of less than 0.5% by weight and containing a mixture of A1) 50 to 95% by weight of lacquer polyisocyanates prepared from 1,6-diisocyanatohexane and having a viscosity at 23°C of 100 to 4000 mPa.cndot.s and an isocyanate content of 16 to 24% by weight and A2) 5 to 50% by weight of isocyanurate group-containing polyisocyanates prepared from cycloaliphatic diisocyanates, and B) a polyol component containing one or more organic polyhydroxyl compounds, wherein components A) and B) are present in amounts corresponding to an NCO/OH equivalent ratio of 0.7:1 to 1.5:1. The invention also relates to the use of these two-component polyurethane coating compositions for the solvent-free coating of any substrates, in particular for the solvent-free sealing of balconies or roofs.
