FIELD: process engineering.
SUBSTANCE: invention relates to chemical processes, particularly, to production of heat isolation gradient coat. Epoxy resin is first mixed with hollow glass microspheres. Then hardener and phosphorus acid glycidyl ethyl ether are added in the following ratio (wt %): epoxy resin - 100; phosphorus acid glycidyl ethyl ether - 15-25; hollow glass microspheres - 25-45; stoichiometric amount of hardener.
EFFECT: higher heat isolation properties.
