FIELD: technological processes.

SUBSTANCE: invention relates to a one-component, high-temperature-stable thermo-curable composition intended for producing a coating, to a method for producing a coating, as well as to a product. One-component curable composition comprises a thermally curable powder composition comprising at least one solid epoxy resin and at least one solid epoxy curing resin. Benzofuran-diepoxide, or modified benzofuran-diepoxide, or a combination of them is used as a solid epoxy resin. Method of obtaining thermally curable powder composition is that the mixture of epoxy resins is melted, mixed, the reaction is stopped and the product is powdered. Method for producing a coating consists in applying the above one-component curable composition to at least one major surface of a substrate selected from the group comprising a metal substrate, a ceramic substrate, a glass substrate or a polymeric substrate. Cured powder composition. Product contains the above substrate having a first main surface and a second main surface, and a coating obtained from the above one-component curable composition on at least one part of the main surface of the substrate.

EFFECT: invention allows to obtain a one-component composition, stable at high temperature, and products with a high glass transition temperature and high strength.
