Abstract of the Disclosure Petroleum derived oil-modified polyurethane compositions incor- porating heat-reflecting and/or e.m. radiation reflecting agents are dis- closed. The compositions may be employed for insulating and protecting a variety of surfaces, substrates and areas, particularly in connection with application to tundra and permafrost. The compositions may also be used to prevent undue expansion and contraction on structures of all types such as runways or roadways, canals, beams, etc. to thereby prevent dis- tortion and cracking; and to prevent deterioration by the sun's rays react- ing on a substrate. The compositions reflect infrared rays from the surface and thereby prevent damage to structures from expansion and contraction or distortion caused by the sun's rays.
