Abstract

a. Procédé pour la fabrication d'une composition résineuse d'imprégnation sans solvant, destinée à revêtir, imprégner et encapsuler l'isolant d'importants composants électriques. b. Procédé caractérisé en ce qu'on fait réagir un mélange d'une résine époxy et une résine époxy liquide avec 0,01 à 0,06 partie d'anhydride maléique et 0,0001 à 0,005 partie d'un catalyseur, de façon à former un époxy diester, qu'on ajoute au produit de la réaction un monomere vinylique, co-réactif avec l'époxy diester et un stabilisant à la température ambiante, on dissout dans le mélange obtenu un anhydride polycarboxylique et un catalyseur à radical libre, on ajoute un accélérateur latent
