Abstract: A method of making a coated abrasive article comprises sequential steps: disposing a curable composition on a major surface of a backing b) adhering abrasive particles to the curable composition; c) at least partially curing the free-radically polymerizable component; and d) at least partially curing the phenolic resin component to provide an at least partially cured composition. The curable composition comprises a phenolic resin component, a free-radically polymerizable component, and an organic polymeric rheology modifier, wherein the organic polymeric rheology modifier comprises an alkali-swellable/soluble polymer, and wherein, on a solid basis, the organic polymeric rheology modifier comprises from 0.001 to 5 weight percent of the phenolic resin component, the free-radically polymerizable component, and the organic polymeric rheology modifier combined. A variant wherein step b) effectively occurs after step c) is also disclosed. Abrasive articles made according to the methods are also disclosed.

Abstract: An abrasive article is presented that includes a first set of shaped abrasive particles with a majority of the first set of shaped abrasive particles are oriented with respect to a backing in a first orientation. The abrasive article also includes a second set of shaped abrasive particles with a majority of the second set of shaped abrasive particles are oriented with respect to the backing in a second orientation, and wherein the second orientation differs from the first orientation. The first and second set of shaped abrasive particles are embedded within a coating layer on the baking.

Abstract: An abrasive article is disclosed. The abrasive article has a backing substrate. The abrasive article also has a laminate joined to the backing substrate. The laminate comprises a hot melt polymer. The abrasive article also has a cured resin composition joined to the laminate opposite the backing substrate. The abrasive article also has abrasive particles joined to the cured resin composition.

Abstract: Various embodiments disclosed relate to an abrasive article (10). The abrasive article (10 includes a backing (12) defining a major surface. The abrasive article (10) includes an abrasive layer including a plurality of tetrahedral abrasive particles (16) attached to the backing (12). The tetrahedral abrasive particles (16) include four faces joined by six edges terminating at four vertices (40, 42, 44, 46). Each one of the four faces contacts three of the four faces, and a major portion of the tetrahedral abrasive particles (16) have at least one of the vertices (40, 42, 44, 46) oriented in substantially a same direction.

Abstract: An open coat abrasive article includes a backing having first and second opposed major surfaces, a make coat resin on at least one major surface of the backing, abrasive particles arranged on the backing at least partially embedded in the make coat resin, and a size coat resin on the first resin and the abrasive particles, wherein the shaped abrasive particles have an average peak count of no greater than about 40,000 per 24 in2. A method of abrading in a body-in-white application is also disclosed.
