More Information
Summary:A structured abrasive article comprises a backing having first and second opposed major surfaces and an abrasive layer securely bonded to the first major surface of the backing. The abrasive layer comprises shaped abrasive composites. Each shaped abrasive composite has four sides, a height, and abase that faces the first major surface of the backing. The shaped abrasive composites have an average height of 410 to 650 microns and an average side length at the base of 550 to 1450 microns. The shaped abrasive composites comprise non-magnetizable shaped abrasive platelets that have an average side length of 150 to 350 microns and an average thickness of 40 to 120 microns. Methods of making and using are also disclosed.
