<p>A single component moisture-hardening coating composition contains from 15 to 70 % by weight of isocyanate forming polyurethane, from 5 to 25 % by weight of clear, liquid, aromatic hydrocarbon resin of low molecular weight and containing OH groups, from 0.2 to 2 % by weight of anti-settling agents, from 10 to 35 % by weight of lamellar diluent, from 2 to 25 % by weight of colorant pigments, from 1 to 5 % by weight of moisture-binders, the remainder being comprised of at least 5 % by weight of a conventional solvent. This coating composition may be normally applied as one layer of at least 20 mum of thickness on a clean and dust-free base and it hardens on its own owing to the penetration of moisture from the surrounding atmosphere. This coating composition is particularly appropriate to protect all types of roofs, to coat concrete, to protect reinforced concrete against corrosion, to coat steel roofs and/or to seal flat roofs covered with asphalted cardboard. </p> |
