Abstract: Provided are abrasive articles, and related methods, that include a flexible abrasive layer having opposed first and second major surfaces, a foam backing bonded to the second major surface, the foam backing being resiliently compressible, and a plurality of slits disposed on the first major surface and penetrating through the flexible abrasive layer and at least partially through the foam backing. In further disclosed embodiments, the abrasive article includes, a flexible abrasive layer having opposed first and second major surfaces, a structured member extending across the second major surface of the flexible abrasive layer, where the structured member and the flexible abrasive layer have respective three-dimensional patterns of discrete, isolated wells that correspond to each other, and a foam backing extending across a major surface of the structured member opposite the flexible abrasive layer, the foam backing being resiliently compressible.

Abstract: Described herein is an improved abrasive material (300) in which the cutting performance is orientation-independent. The abrasive material (300) comprises an abrasive structure (310) including a plurality of elongate abrasive elements (320, 330) aligned to be define a first open square. A plurality of pyramidal abrasive elements (340, 350) arranged in a second open square are located within the first open square defined by the elongate elements (320, 330).

Abstract: A method of finishing a metallic surface includes the steps of: disposing a mask layer onto an initial metallic surface of a substrate, etching at least a portion of the initial metallic surface with an etchant to provide an etched surface, and separating the etchant from the etched surface. The etched surface is smoother than the initial metallic surface. On a depth basis: the etchant etches said at least a portion of the mask layer and said at least a portion of the initial metallic surface at substantially the same rate; and/or the etchant penetrates said at least a portion of the mask layer and etches said at least a portion of the initial metallic surface at substantially the same rate. A substrate finished by the disclosed method and a kit for practicing the method are also disclosed.

Abstract: A coated abrasive article (10) having a flexible backing (12) and an abrasive coat (20) attached to the backing (12) by a tie coat (18), wherein the tie coat (18) is liquid-softenable such that the tie coat (18) maintains the flexible backing (12) in a substantially rigid state when the tie coat (18) is dry and allows the backing (12) to flex when the tie coat (18) is in its softened state.
