FIELD: chemistry.

SUBSTANCE: composition includes a binder and a light filler and further comprises carbamide-furane resin of the brand FK and a curing catalyst of the brand OK in the amount of 10 wt % of resin. Wherein an aluminium-chromium-phosphate binder is selected as a binder, and hollow aluminosilicate microspheres with a particle size of 150 to 280 microns are selected as a lightweight filler in the following ratio of components, wt %: an aluminium-chromium-phosphate binder 25-34, hollow aluminosilicate microspheres 55-69.5, a curing catalyst of the brand OK 0.5-1, carbamide-furane resin of the brand FK 5-10.

EFFECT: increasing the mechanical properties of refractory lightweight heat-insulating products and reducing the heat losses from a heat-insulated surface.
