An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group define a first non-shadowing distribution relative to each other.

Abrasive particles having particular shapes and methods of forming such particles

The present invention relates generally to coated abrasive articles that include a blend of abrasive particles, an increased tear resistance, or combinations thereof, as well as methods of making and using said coated abrasive articles.

Coated abrasives having a blend of abrasive particles and increased tear resistance

A coated abrasive article including a plurality of shaped abrasive particles overlying a backing, the coated abrasive article having a plain-carbon steel grinding lifespan of at least about 5500 g/in.

Abrasive article including shaped abrasive particles

An engineered coated abrasive product having a backing, a frontfill coat, a make coat, and/or a size coat, wherein at least one of the coats includes fibrillated fibers. The coated abrasive product is capable of improved inter-layer adhesion, retention of abrasive grains, and/or maintenance of abrasive grains in a more desirable orientation for grinding.

Abrasive products having fibrillated fibers

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.

High-performance resin for abrasive products

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, a nanoparticle binder, a dual function material, and a cross-linking agent. These green unfired abrasive aggregates can also be used in free abrasive products and bonded abrasive products.

Coated abrasive aggregates and products containg same

An abrasive article includes a backing having a major surface, an adhesion promoting layer overlying the major surface of the backing, and a make layer directly contacting the adhesion promoting layer. The adhesion promoting layer has a thickness of at least about 10 microns and is formed of a polar thermoplastic material, a cross-linkable polymer, or blends thereof.

Abrasive article with adhesion promoting layer

A macro-porous abrasive article includes a spun lace substrate having a macro-porous structure and a coating. The coating is made of a resin binder and abrasive aggregates. The abrasive aggregates are formed from a composition of abrasive grit particles and a nanoparticle binder. The coating is at least partially embedded in the substrate. A method for making the macro-porous abrasive article includes combining abrasive aggregates of abrasive grit particles and a nanoparticle binder with a resin binder to form a slurry. The slurry is applied to a macro-porous support structure so that the slurry at least partially penetrates the substrate. The resin is then cured to bond the aggregate grains to the substrate.

Rigid or flexible, macro-porous abrasive article

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.

Coated abrasive products containing aggregates

A method of forming a coated abrasive article includes providing a composite binder and abrasive grains on a backing. The composite binder includes at least 5 wt % of a particulate filler having an average particle size of less than 100 nm. The method also includes curing the composite binder.

Method of forming structured abrasive article

A coated abrasive article includes a backing and fused alumina-zirconia abrasive grains attached to the backing with a binder. The fused alumina-zirconia abrasive grains include between about 35 wt % and about 45.5 wt % ZrO+HfO, between about 43.7 wt % and about 65 wt % AlO, less than about 0.8 wt % SiOand less than about 10 wt % other oxides. The fused alumina-zirconia abrasive grains simultaneously satisfy both a granulometric and densimetric condition.
