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.
