FIELD: pipeline heat insulation in civil and industrial building.
SUBSTANCE: coating composition includes 5-95 vol.% of polymeric binder and 5-95 vol.% of hollow microspheres. At least one composition layer is coated onto substrate and dried. Said polymeric binder contains 10-90 % of (co)polymer selected from acrylate homopolymer, styrene-acrylate copolymer, butadiene-styrene copolymer, polyvinylchloride, polyurethane, vinylacetate polymer or copolymer or mixture thereof. Binder also contains 10-90 vol.% of water and surfactant mixture. hollow microspheres have particle size of 10-500 mum and bulk density of 50-650 kg/m3, and made from glass, ceramic, polymers, sol or mixture thereof.
EFFECT: improved corrosion resistance and heat insulation of coated substrate; increased adhesion properties.
