Abstract: An abrasive product includes a plurality of abrasive particles and a resin cured with a polythiol group. A method of preparing the abrasive product includes contacting the plurality of abrasive particles with a curable composition that includes a resin and a polythiol group, and curing the curable composition to produce the abrasive product. A method of abrading a work surface includes applying an abrasive product to a work surface in an abrading motion to remove a portion of the work surface. A curable composition includes a formaldehyde resin and a polythiol group. A formaldehyde resin is crosslinked by a polythiol group. A method of crosslinking the formaldehyde resin includes reacting the polythiol group with the formaldehyde resin.
Abstract: A bonded abrasive article is provided that includes abrasive grains within a bond matrix, the abrasive grains including cubic boron nitride (cBN) and the bond matrix including a polycrystalline ceramic phase. The bonded abrasive may have a Modulus of Rupture (MOR) of not less than about 40 MPa. Certain embodiments may have porosity, such as greater than about 5.0 vol %.
Abstract: Abrasive tools contain abrasive grains oriented in an array according to a non-uniform pattern having an exclusionary zone around each abrasive grain, and the exclusionary zone has a minimum dimension that exceeds the maximum diameter of the desired grit size range for the abrasive grain. Methods for designing such a self-avoiding array of abrasive grain and for transferring such an array to an abrasive tool body are described.

Abstract: A coated abrasive product includes a particulate material containing green, unfired abrasive aggregates having a generally spheroidal or toroidal shape, the aggregates formed from a composition comprising abrasive grit particles and a nanoparticle binder. Free abrasive products, bonded abrasive products, and the particulate material also contain aggregates.
Abstract: An abrasive article includes an abrasive layer having an array of protrusions. The abrasive layer has a thickness not greater than about 500 mils. The abrasive article is free of a backing layer.
Abstract: A surface-modified abrasive grain includes an abrasive grain as a substrate, and a film on the abrasive grain that includes a relatively hydrophilic silane component and a relatively hydrophobic silane component. The film can be a single film layer or multiple film layers, wherein a film layer most proximal to the abrasive grain has a predominately hydrophilic silane component, and a film layer more distal to the abrasive grain includes predominately a relatively hydrophobic silane component. Coated abrasive products and bonded abrasive products include the surface-modified abrasive grains.
Abstract: A nail care system for buffing and polishing fingernails and toenails is disclosed. The system includes a nail care strip that includes a layer of a liquid silicone resin formulation and abrasive grains.

Abstract: A method of cleaning a household kitchen or bath solid surface includes placing a cleaning article on the solid surface that includes a foreign matter. The method further includes abrading the solid surface with the cleaning article to remove the foreign matter. The cleaning article includes a layer of a liquid silicone rubber formulation and abrasive grains.
Abstract: An abrasive article includes a base, an abrasive member comprising three distinct phases bonded to each other including abrasive particles, a metal matrix, and an infiltrant. The abrasive article further includes a backing region between the abrasive member and the base, wherein the backing region comprises a laser welded bond joint.
Abstract: An abrasive article comprising abrasive grains bonded with a binder comprising a matrix polymer and an amphiphilic block copolymer dispersed in the matrix polymer. The abrasive article can be a coated abrasive article, such as an engineered abrasive article, including a backing. The binder can bind the abrasive grains to the backing.
Abstract: A cloth backing for an abrasive article is treated by combining a phenolic resin, a latex and a colloidal silicon oxide composition to prepare a colloidal formulation, which is then applied to the cloth backing and cured. Coated abrasive articles are formed by applying a make coat formulation to the treated cloth backing, applying an abrasive and then curing the make coat formulation.
Abstract: A coated abrasive article includes a backing having a surface, a plurality of abrasive regions overlying the surface in each of the first and second portions, and at least one macro-channel. The surface of the backing has a shape defined by an outer contour. A bisecting axis divides the shape into first and second portions. Each abrasive region includes a binder and a plurality of abrasive grains in contact with the binder. The abrasive grains have an average grain size of not greater than about 200 microns. The at least one macro-channel defines a passageway extending between a pair of adjacent abrasive regions and terminating at openings at the outer contour within each of the first and second portions. The macro-channel has an average channel width of between about 0.1 millimeters to about 5 millimeters and is substantially free of the binder and the abrasive grains.
Abstract: An article includes a packaging material comprising a self-supporting wall having a water vapor transfer rate of not greater than 0.001 g/m2-day. The packaging material defines an enclosed volume. The article further includes a bonded abrasive article disposed within the enclosed volume. The bonded abrasive article includes abrasive grains dispersed in a polymer matrix. The polymer matrix includes hygroscopic material.
Abstract: An abrasive article includes a fabric comprising a front face and a back face. The front face is formed of first knitted yarns. Each yarn of the first knitted yarns includes a plurality of filaments. A plurality of threads intertwines with the first knitted yarns and extending between the front face and the back face. The plurality of threads defines a hollow space between the front face and the back face. The abrasive article also includes abrasive grains adhered to the front face of the fabric.
