ABSTRACT:
Abrasive articles comprising a cured thermosetting binder and abrasive grains. The binder is prepared with a poly-functional molecule comprising at least two functional groups selected from the group consisting of carboxyl and anhydride, and a crosslinking agent which is selected from the group consisting of a mono(hydroxyalkyl)urea comprising a single urea group, a single hydroxyl group, and at least two carbon atoms disposed between the urea group and the hydroxyl group, and 2-oxazolidone. The abrasive articles comprise bonded, nonwoven or coated abrasive articles.
