Beschreibung
Zusammenfassung:	The disclosure relates to a curable composition comprising: a polymerizable epoxy- acrylate resin composition having a complex viscosity at 25°C and 1 Hz frequency of at least about 4500 Pa-s and a probe tack peak force of at least about 300 kPa; and abrasive particles partially or fully embedded in the polymerizable epoxy-acrylate resin composition. The disclosure also relates to cured compositions formed from such curable compositions, wherein the abrasive particles are partially or fully embedded in the cured composition. In addition, the disclosure relates to abrasive articles made from such cured compositions as well as methods for making abrasive articles. L'invention concerne une composition durcissable comprenant : une composition de résine époxy-acrylate polymérisable ayant une viscosité complexe à 25 °C et une fréquence de 1 Hz d'au moins environ 4500 Pa-s et une force maximale d'adhérence à une sonde d'au moins environ 300 kPa ; et des particules abrasives partiellement ou totalement noyées dans la composition de résine époxy-acrylate polymérisable. L'invention concerne également des compositions durcies formées à partir de telles compositions durcissables, les particules abrasives étant partiellement ou totalement noyées dans la composition durcie. De plus, l'invention concerne des articles abrasifs fabriqués à partir de telles compositions durcies, ainsi que des procédés pour la fabrication d'articles abrasifs.
