Abstract: A coated abrasive article comprises a backing having first and second opposed major surfaces. A make layer is bonded to the first major surface. Agglomerate grinding aid particles are directly bonded to the make layer. At least a portion of the agglomerate grinding aid particles comprise grinding aid particles retained in a binder, and are arranged according to an open predetermined pattern. Abrasive particles are directly bonded to the make layer in spaces between the agglomerate grinding aid particles. A size layer is directly bonded to the make layer, agglomerate grinding aid particles, and abrasive particles. A method of making a coated abrasive article, in which the agglomerate grinding aid particles are deposited onto a curable make layer precursor prior to depositing abrasive particles onto the curable make layer precursor in spaces between the agglomerate grinding aid particles is also disclosed.

Abstract: A method of making a coated abrasive article includes: depositing precisely-shaped abrasive platelets into precisely-shaped cavities in a production tool; depositing diluent abrasive particles onto the production tool; contacting the precisely-shaped abrasive platelets and the diluent abrasive particles with a curable make layer precursor disposed on a major surface of a backing; separating the tool from the precisely-shaped abrasive platelets and the diluent abrasive particles; and at least partially curing the curable make layer precursor to provide an at least partially cured make layer precursor. Coated abrasive articles preparable by the method are also disclosed.

Abstract: An abrasive article includes a first plurality of abrasive particles and a second plurality of abrasive particles. The first plurality of abrasive particles differ in at least one of a size, an average weight and a shape from the second plurality of abrasive particles. The first plurality of abrasive particles are spaced from the second plurality of abrasive particles by at least a minimum distance in the x-axis direction, and both the first plurality of abrasive particles and the second plurality of abrasive particles extend in similar paths to one another with respect to the y-axis.

Abstract: A coated abrasive article comprises a backing having first and second opposed major surfaces, a make layer disposed on at least a portion of the first major surface and bonding abrasive particles to the backing, a size layer overlaid on at least a portion of the make layer and the abrasive particles, and an optional supersize layer. At least one of the size layer or the optional supersize layer comprises an at least partially cured resole phenolic resin and an organic polymeric rheology modifier, and wherein the amount of the at least partially cured resole phenolic resin comprises from 75 to 99.99 weight percent of the combined weight of the at least partially cured resole phenolic resin and the organic polymeric rheology modifier. A method of making the coated abrasive article is also disclosed.

Abstract: Compositions that are curable to polythioether polymers are provided, comprising: a) a dithiol monomer; b) a diene monomer; c) a radical cleaved photoinitiator; d) a peroxide; and e) an amine; where the peroxide and amine together are a peroxide-amine redox initiator. In some embodiments, the amine is a tertiary amine. In some embodiments, the amine is selected from the group consisting of dihydroxyethyl-p-toluidine, N,N-diisopropylethylamine, and N, N, N′, N″, N″-pentamethyl-diethylenetriamine. In some embodiments, the peroxide is selected from the group consisting of di-tert-butyl peroxide, methyl ethyl ketone peroxide, and benzoyl peroxide. In some embodiments, the composition may additionally comprise a polythiol monomer having three or more thiol groups.

Abstract: In methods and systems of making an abrasive article, abrasive particles are loaded to a distribution tool including a plurality of upper walls defining a plurality of spacing slots, and a plurality of lower walls defining a plurality of distribution slots. The spacing slots are open to the distribution slots, which are open to a lower side of the tool. The loaded particles are spaced and distributed from the distribution tool to a major face of a backing web below the lower side and moving relative to the tool in a machine direction. The upper walls space the particles in the machine direction. The particles distributed by the lower walls undergo an orientation sequence in which each particle is oriented into a column aligned along the machine direction. The upper walls can be disposed oblique to the lower walls. The upper and lower walls can have pointed upper portions.
