The curable composition is useful for preparing treated backings and coated abrasive articles.

Composition, treated backing, and abrasive articles containing the same

An abrasive article is presented which includes a backing having a front and back surface, and an abrasive coating bonded to the front surface of the backing. The abrasive coating comprises a homogeneous mixture of a plurality of abrasive particles, a binder and a grinding aid. The binder serves to bond the abrasive coating to the backing and the grinding aid comprises at least 1% by weight of the abrasive coating, but not more than 50% by weight. It is preferred that the abrasive coating consists essentially of a plurality of precisely shaped abrasive composites. Methods of making and using the abrasive articles are also presented.
