Abstract

Two-component polyurethane coating compositions essentially containing A) a polyisocyanate component containing A1) certain aliphatic polyisocyanates and A2) certain aromatic polyisocyanates, B) a polyol component containing B1) selected polycaprolactone polyols and/or selected polyether polyols, and optionally B2) other organic polyhydroxyl compounds, and C) known additives used in surface coating technology; and the application of such coating compositions for the manufacture of floor sealers or thin coatings.
