Patent

CA 2741774

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.

L'invention concerne une composition monocomposant d'un revêtement pulvérulent thermodurcissable qui comprend une résine contenant des insaturations réactives, toutes ces insaturations réactives étant des liaisons doubles carbone carbone reliées directement à un groupe électroattracteur; un système d'amorçage thermique qui comprend un peroxyde choisi dans le groupe des composés représentés par la formule (1), dans laquelle R1 et R2 représentent chacun indépendamment un alkyle éventuellement substitué comportant de 1 à 30 atomes C, les 1 à 30 atomes C n'incluant pas les atomes C des substituants, ou un aryle éventuellement substitué comportant de 6 à 18 atomes C, les 6 à 18 atomes C n'incluant pas les atomes C des substituants, et un coagent de réticulation choisi dans le groupe des vinyléthers, des vinylétheruréthannes, des vinylesters, des vinylamides, des itaconates, des énamines, des vinylurées et des mélanges de ceux-ci.
