FIELD: chemistry.
SUBSTANCE: anticorrosion and heat-insulating coating is made from an water-suspension composition with viscosity of 1-100 Pa·s, which includes a mixture of polymer binder 5-95 vol. % with filler - hollow microspheres 5-95 vol. %. The polymer binder is a water-emulsion polymer latex composition containing a (co)polymer selected from a group comprising an acrylate homopolymer, a styrene-acrylate, a butadiene-styrene and a vinyl acetate copolymer, polystyrene, butadiene polymer or a mixture thereof, a surfactant, water and ε-caprolactam. The filler used is a mixture of hollow polymer microspheres with diameter of 10-90 mcm and packed density of 25-40 kg/m3 and hollow glass microspheres, taken in ratio of 1:1.
EFFECT: invention increases resistance of the coating to thermal oxidative degradation, adhesion to hot surfaces as well as tensile strength and reduces specific weight.
