Patent

CA 2303931

The invention relates to a radiation-curable binder composition for powder paint formulations. The binder composition comprises: a) a solid polymer with an amount of unsaturation of between 300 and 1800 g per mole of unsaturated group (WPU) and with a molecular weight (Mn) of between 800 and 5000 g per mole and b) a cross-linker comprising units of a prepolymer having a molecular weight (Mn) higher than 400 and units of a vinyl ether or an unsturated alcohol, the number of polymerizable unsaturations of the cross-linker being higher than or equal to 2.

L'invention concerne une composition liante durcissable sous rayonnement qui convient pour des préparations de peinture en poudre. Ladite composition liante comprend a) un polymère solide présentant une quantité d'insaturations du groupe insaturé (WPU) comprise entre 300 et 1800g par mole, et un poids moléculaire (Mn) compris entre 800 et 5000g par mole; et b) un agent de réticulation comprenant des unités d'un prépolymère présentant un poids moléculaire (Mn) supérieur à 400, et des unités d'un éther vinylique ou d'un alcool insaturé, la quantité d'insaturations polymérisables de l'agent de réticulation étant au moins égal à 2.
