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.

Abstract: A method of making a coated abrasive article includes disposing a precursor make layer on a major surface of the backing, optionally partially curing the precursor make layer to provide a partially cured precursor make layer, disposing abrasive particles; partially embedding abrasive particles in the optionally partially cured precursor make layer; and further curing the optionally partially cured precursor make layer to form a make layer. The precursor make layer comprises components comprising: a) 50 to 97.99 percent by weight of phenol-formaldehyde resin; b) 1 to 49 percent by weight of resorcinol-formaldehyde resin; c) 1 to 49 percent by weight of at least one compound having at least one free-radically polymerizable group; and d) 0.01 to 1 percent by weight of a free-radical initiator. A size layer and/or supersize layer may be disposed over the make layer and abrasive articles. Coated abrasive articles made by the method are also disclosed.

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 comprises: a substrate comprising strands forming first void spaces between strands; a laminate joined to the substrate, wherein the laminate comprises a surface opposite to the substrate; a resin composition joined to the surface of the laminate. First and second portions of the surface of the laminate have respective first and second surface free energies that are different. Another abrasive article comprises: a substrate comprising strands forming first void spaces between strands; a laminate joined to the substrate, wherein the laminate comprises a first polymer and a second polymer; a resin composition joined to the laminate; In both embodiments, abrasive particles are joined to the resin composition, and a plurality of second void spaces extends through the laminate coinciding with first void spaces in the porous substrate. A method of making abrasive articles is also disclosed.
