Abstract: An adhesion promoter comprises a reaction product of: a) a polyepoxide; b) an aminosilane represented by the formula HNR1R2. R1 and R2 independently represent —Z—SiL3. Each Z independently represents a divalent linking group having from 1 to 12 carbon atoms, and each L independently represents a hydrolyzable group; and c) an isocyanatosilane represented by the formula O═C═N—Z—SiL3, wherein Z and L are as previously defined. The adhesion promoter may be used to treat a surface of a substrate such as an abrasive particle, which may be included in a resin-bond abrasive article.

Abstract: A method of shape sorting abrasive particles involves disposing initial crushed abrasive particles with agitation against the surface of a tool, the surface defining a plurality of shaped cavities having an average aspect ratio of at least 1.2, thereby causing a first portion of the initial crushed abrasive particles to become retained within at least some of the shaped cavities, and causing a second portion of the initial crushed abrasive particles to remain as loose particles on the surface. Substantially all of the shaped cavities contain at most one abrasive particle. The second portion of the initial crushed abrasive particles is separated from the tool. The first portion of the initial crushed abrasive particles is then separated from the tool and isolated as loose sorted crushed abrasive particles. The average aspect ratio of the loose sorted crushed abrasive particles is greater than that of the initial crushed abrasive particles.

Abstract: A packaging system for abrasive articles that includes a container portion sized to receive the abrasive articles. The system also includes a lid portion that removably couples to the container portion. The system also includes a rechargeable moisture control feature, housed within the packaging system. The rechargeable moisture control feature removes moisture from an atmosphere within the packaging system. The system also includes a moisture indicator that indicates whether moisture is present within the container portion.

Abstract: Methods of making abrasive articles involve adhering shaped abrasive particles to a reinforcing member according to a predetermined pattern and optionally orientation, and depositing a space-filling binder precursor on the reinforcing member and shaped abrasive particles to provide a filled abrasive preform, disposing another reinforcing member onto the filled abrasive preform, and curing the abrasive article precursor to form the abrasive articles. In some aspects, multiple abrasive preforms are stacked on each other. Bonded abrasive wheels preparable according to the methods are also disclosed.
