Abstract

L'invention concerne un procédé de fabrication d'un article abrasif revêtu, comprenant les étapes séquentielles suivantes : disposition d'une composition durcissable sur une surface principale d'un support ; b) mise en adhérence de particules abrasives avec la composition durcissable ; c) durcissement au moins partiel du composant polymérisable par voie radicalaire ; et d) durcissement au moins partiel du composant de résine phénolique afin d'obtenir une composition au moins partiellement durcie. La composition durcissable comprend un composant résine phénolique, un composant polymérisable par voie radicalaire, et un modificateur de rhéologie polymère organique, le modificateur de rhéologie polymère organique comprenant un polymère soluble/gonflable dans les alcalis et, sur une base solide, le modificateur de rhéologie polymère organique comprenant de 0,001 à 5 % en poids du composant résine phénolique, du composant polymérisable par voie radicalaire et du modificateur de rhéologie polymère organique combinés. L'invention concerne également une variante dans laquelle l'étape b) est exécutée efficacement après l'étape c). L'invention concerne également des articles abrasifs fabriqués selon les procédés.
