FIELD: chemical industry. SUBSTANCE: described is composition for coatings comprising polyphenylenepolymethylene polyisocyanates, polyester polyol, second polyol containing no carboxy groups and diluent. Polyester polyol is product of reaction of drethylene glycol with adipic acid or triethylene glycol with distilled thallic oil. Second polyol is N, N, N', N'-tetraxis-(hydroxypropyl)ethylene diamine, and diluent is tris-(chloroalkyl)phosphate, ratios of components, wt parts, being as follow: said polyesterpolyol, 100; said second polyol, 50-180; said diluent, 11-120; polyphenylene polymethylene polyisocyanates, 108-400. EFFECT: protection of hydroinsulation of industrial projects based on simple and accessible components. 2 cl, 16 ex, 1 tbl
