FIELD: chemistry.
SUBSTANCE: invention relates to production of coatings having improved strength, thermal, fire and weather resistance properties for protecting pipelines of heat supply systems and air ducts of hot-air heating and ventilation systems. The power-saving coating composition contains epoxy resin ED-20, curing agent diethylenetriamine DETA - a curing agent based on aliphatic amines, reactive rubber SKN-30KTRA - low-molecular weight copolymer of butadiene with acrylonitrile, containing terminal carboxyl groups, filler - glass or ceramic microspheres with size of 40-120 mcm, muscovite mica.
EFFECT: obtained composition has high water impermeability, strength and elasticity, improved heat insulation properties, fire, chemical and weather resistance.
