摘要
Compsn. (I) comprises 15-40 wt.% polyurethane-forming isocyanate (II), 5-25 wt.% light-stable, OH gp.-contg. tar (III), 0.5-2 wt.% antisettling agent, 15-35 wt.% lamellar extender, 5-25 wt.% colouring pigments, 1-5 wt.% moisture-combining agent, and remainder (less than 5 wt.%) conventional paint solvent. (I) is applied to clean, dust-free surface and allowed to harden through contact with atmospheric humidity. Protection of roofs, coating concrete, corrosion-protection of reinforced concrete. (I) is workable at temps. below 5 deg.C, and at high humidity, is self-levelling, protects against ultra-violet radiation, has good light and heat reflection values, high pore-sealing effect even in thin layers (e.g., 50 microns), good elasticity and adhesion, can be reworked even after weathering, and does not crack on hardening even in thick layers (e.g., over 200 microns.).
