More Information
Summary:A coated abrasive article comprising: (a) a backing; (b) at least one layer comprising a plurality of precisely shaped abrasive particles that comprise abrasive grits and a free-radically polymerized binder, wherein said precisely shaped particles have vertexes and (c) a bonding medium which serves to adhere said precisely shaped particles to said backing; wherein the precisely shaped particles are randomly disposed on the backing such that at least a portion of said particles are oriented with said vertexes pointing toward said backing.
