A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, wherein at least 5% of the plurality of abrasive particles is tooth-shaped abrasive particles.

Abrasive articles and methods of forming same

A coated abrasive article comprising a backing, an adhesive layer disposed in a discontinuous distribution on at least a portion of the backing, wherein the discontinuous distribution comprises a plurality of adhesive contact regions and at least one shaped abrasive particle is disposed on a majority of each of the discrete adhesive contact regions, wherein at least 50% of the shaped abrasive particles comprise a predetermined side orientation and have a tilt angle of at least 45 degrees, wherein the shaped abrasive particles comprise a polycrystalline material and are free of binder, wherein the first plurality of discrete adhesive contact regions comprise a predetermined two-dimensional shape as viewed from above, and wherein each of the discrete contact regions comprises a length, a width, or a combination thereof that substantially corresponds to a dimension of the at least one abrasive particle.

Abrasive particles having particular shapes and methods of forming such particles

Systems and methods include providing a coated abrasive article with a substrate formed from a plurality of hygroscopic fibers, an abrasive layer comprising a make coat, a size coat, a supersize coat, or combinations thereof disposed on a first side of substrate, and an anti-curl layer disposed on a second side of the substrate. The polymer-based anti-curl layer allows the coated abrasive article to achieve a change in curl between −5 millimeters and 25 millimeters, the change in curl being expressed as the curl of the coated abrasive article in millimeters at 90% relative humidity minus the curl of the coated abrasive article in millimeters at 20% relative humidity. The coated abrasive article exhibits substantially no loss of grinding performance, burst speed, or a combination thereof as compared to coated abrasive articles free of the anti-curl layer.

Rigid backsize to prevent fiber disc curling

An abrasive article including a substrate; and an abrasive layer overlying the substrate, where the abrasive layer includes a blend of abrasive particles including a first type of abrasive particle comprising a polycrystalline material and having a first average friability F, and a second type of abrasive particle comprising a polycrystalline material and having a second average friability, F, where the blend comprises an average friability difference, ΔF=|F−F|, within a range of at least 0.5% to not greater than 80%.

Abrasive articles including a blend of abrasive particles and method of forming and using the same

A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, and the plurality of abrasive particles including tapered abrasive particles having a taper fraction standard deviation of at least 0.025 and not greater than 0.090.

An abrasive particle can include a coating overlying at least a portion of a core. In an embodiment, the coating can include a first portion overlying at least a portion of the core and a second portion overlying at least a portion of the core, wherein the first portion can include a ceramic material and the second portion can include a silane or a silane reaction product. In a particular embodiment, the first portion can consist essentially of silica. In another particular embodiment, the first portion can include a surface roughness of not greater than 5 nm and a crystalline content of not greater than 60%.

Abrasive particle including coating, abrasive article including the abrasive particles, and method of forming

An abrasive article including a substrate; and an abrasive layer overlying the substrate, where the abrasive layer includes a blend of abrasive particles including a first type of abrasive particle comprising a polycrystalline material and having a first average friability F, and a second type of abrasive particle comprising a polycrystalline material and having a second average friability, F, where the blend comprises an average friability difference, &#x394;F=|F&#x2212;F|, within a range of at least 0.5% to not greater than 80%.

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.

The present disclosure relates generally to coated abrasive articles that include a grinding aid aggregates in a make coat, a size coat, a supersize coat, or combinations thereof, as well as methods of making coated abrasive articles.
