摘要:
An abrasive article with a backing having a first major surface and a second major surface opposed to the first major surface. A three-dimensional abrasive layer attached to the first major surface, the three-dimensional abrasive layer comprising a plurality of shaped abrasive composites spaced apart by a plurality of land areas between the shaped abrasive composites, each of the shaped abrasive composites comprising a top surface and a sidewall, and the plurality of shaped abrasive composites and the plurality of land areas both formed from abrasive particles dispersed within an organic binder. A preconditioning indicator located on the top surface of at least some of the plurality of shaped abrasive composites and a persistent indicator located on at least some of the plurality of land areas.
