An abrasive article is provided that includes a bond system formed from a binder precursor and about 15 % by weight or less of a wax-containing modifier. An abrasive article that includes the bond system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a bond system formed from a composition containing substantially no wax-containing modifier.
L'invention concerne un article abrasif comprenant un système de liaison formé d'un précurseur de liant et d'environ 15 % en poids ou moins d'un modificateur contenant une cire. Avec un article abrasif comprenant ce système de liaison, la surface abrasée d'une pièce de travail mesurée dans un test de ponçage de bois à force normale (Woodsanding Normal Force Test) est accrue par rapport celle obtenue avec un article abrasif comprenant un système de liaison formé d'une composition sensiblement dépourvue de modificateur contenant de la cire.
