FIELD: chemistry.
SUBSTANCE: invention relates to a single-component thermally solidified powder coating, which contains resin with reactive unsaturation, in which all the said unsaturation represents double bonds carbon-carbon, directly bound with an electron-acceptor group, a thermal initiation system, which contains peroxide, selected from the group of compounds, represented by formula , where R1 and R2, each, independently represent optionally substituted alkyl with 1-30 C-atoms, in which 1-30 C-atoms do not include C-atoms of substituents, or optionally substituted aryl with 6-18 C-atoms, in which 6-18 C-atoms do not include C-atoms of substituents, and a cross-linking agent, selected from the group of vinyl ethers, vinylurethane ethers, vinyl esters, vinylamides, itaconates, enamines, vinyl ureas and their mixtures.
EFFECT: invention provides the powder coating composition, which is easily processed in an extruder and which can be partially or fully thermally solidified at low temperatures.
