chemical industry. SUBSTANCE: described is heat-accumulating material composed of polymeric binder and heat-accumulating agent. Polymeric binder is composition based on hydroxyl-containing oligodiene, polyisocyanate, glycerol and urethane-formation catalyst, and heat-accumulating agent is crystallohydrate of inorganic salt that affords crystallization water content of at least 17% in heat-accumulating material, ratio of components is as follows, wt.%: hydroxyl-containing oligodiene, 100; polyisocyanate, 20-38; glycerol, 1-5; urethane formation catalyst, 0.01-3.0; crystallohydrate of inorganic salt that affords crystallization water content of at least 17%, 50-200. EFFECT: coatings resistant to high-temperature load effects that develop during fires. 2 cl, 1 tbl
