This invention relates to thermally-stable, polyglycidyl-terminated polyesters from diglycidyl phthalates and carboxylated polyesters. The resulting resins, when blended and cured with other carboxylated polyesters, are improved binders for powder coating and other applications. The invention also relates to polyglycidyl ester-based powder coating compositions containing these resins. The powder coating compositions have a Tg of about 50 °C or greater and cure to a thermoset in about 20 minutes or less at about 200 °C to about 250 °C, and preferably in about 10 minutes or less at about 200 °C.

L'invention concerne des polyesters à terminaison polyglycidyle, stables à la chaleur, produits à partir de diglycidyl phtalates et de polyesters carboxylés. Les résines obtenues, une fois mélangées et durcies avec d'autres polyesters carboxylés, constituent des liants améliorés pour le revêtement par poudre et autres applications. L'invention concerne également des compositions pour revêtement par poudre à base d'ester de polyglycidyle contenant ces résines. Les compositions de revêtement par poudre présentent une température de transition vitreuse supérieure ou égale à environ 50 ~C et se thermodurcissent en environ 20 minutes ou moins, à une température comprise entre 200 et 250 ~C approximativement, et de préférence en environ 10 minutes au moins à 200 ~C approximativement.
