FIELD: technological processes.
SUBSTANCE: present invention relates to the composition for a heat-resistant powder coating. Composition comprises at least two silicone resins which have different glass transition temperatures and/or different melt viscosities, acrylic bifunctional resin, which contains hydroxide and glycidyl functional groups, which contain mica filler and optional additives. When applied to the substrate, the composition is capable of curing, while forming a heat-resistant coating on the surface of the substrate. Present invention also relates to the use of the composition as per the present invention for coating a substrate, as well as to the bases, which are coated with the compositions as per the present invention.
EFFECT: invention ensures obtaining the coatings that have increased resistance to high temperature impact and a high temperature cycle and improved adhesion.
