FIELD: chemistry. ^ SUBSTANCE: invention relates to thermo-reactive heat-resistant silicon powder compositions for coating used on substrates which can be subjected to high temperature action. Claimed is the powder composition for coating containing, in addition to polysiloxane, 0.01-90 weight % particles of inorganic glass, which are melted and flow within temperature range of 300C-700C, at which organic components of coating burn out. At such temperatures, glass particles are capable of filling voids in films formed from coating powders, and preventing adhesion damage to coating on a substrate. ^ EFFECT: elaboration of powder composition for coating with excellent heat-resistant characteristics including resistance to adhesion damage (splitting and flaking-off) under high temperatures. ^ 11 cl, 2 tbl, 2 ex |
