Abstract: A structured abrasive article comprises a backing with a topographically structured abrasive layer secured thereto. The topographically structured abrasive layer comprises precisely-shaped abrasive composites. A solid overlayer comprising eroding particles with a Mohs scale hardness of at least 4 and a water-soluble polymer is disposed on at least a portion of the topographically structured abrasive layer. Methods of making and using the structured abrasive articles are also disclosed.

Abstract: An abrasive comprising abrasive particles and an adhesive matrix is provided, with the abrasive particles being distributed in the adhesive matrix, wherein the abrasive particles comprise aluminum hydroxide abrasive particles, and the adhesive matrix comprises a triacrylate, a diacrylate and an initiator. The abrasive article prepared using the abrasive of the present invention has proper wear resistance and can be used to a clean LCD panel surface without scratching the ITO coating on an LCD panel surface.
