HEAT-CURABLE POWDER COATING COMPOSITION

摘要

The invention relates to a one component heat curable powder coating composition comprising a resin containing reactive unsaturations and wherein all said reactive unsaturations are carbon carbon double bonds connected directly to an electron withdrawing group, a thermal initiation system comprising a peroxide chosen from the group of compounds represented by formula (1), wherein R1 and R2 each independently stand for an optionally substituted alkyl of 1 to 30 C-atoms, wherein the 1 to 30 C-atoms do not include the C-atoms of the substituents or for an optionally substituted aryl of 6 to 18 C-atoms, wherein the 6 to 18 C-atoms do not include the C-atoms of the substituents, and a co-crosslinker chosen from the group of vinylethers, vinyletherurethanes, vinylesters, vinylamides, itaconates, enamines, vinylureas and mixtures thereof.
