Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Abrasive article including shaped abrasive particles comprising a particular toothed body

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface. The side surface can includes a toothed portion. The toothed portion can comprise a plurality of teeth. Each one of the teeth can have the same height.

Abrasive article including shaped abrasive particles having a tooth portion on a surface

Method of making shaped abrasive particles and articles comprising forming a flange from overfilling

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

Abrasive article including shaped abrasive particles

The present invention relates generally to fixed abrasive articles comprising: abrasive particles; a binder composition; and an abrasive performance enhancing composition, wherein the abrasive particles are disposed on or in the binder composition, and wherein the abrasive performance enhancing composition is disposed overlying the abrasive particles or binder composition or both. The abrasive performance enhancing composition comprises a mixture comprising a lubricant and an anti-wear agent. In particular embodiments the abrasive performance enhancing composition further comprises a fixative material.

Abrasive articles including an abrasive performance enhancing composition

An abrasive article has an abrasive portion with an organic bond and abrasive particles. The abrasive article has a non-abrasive portion (NAP) mounted to the abrasive portion. The NAP includes molding compound (MC) having chopped strand fibers (CSF). The CSF can be coated with a thermoplastic coating having a loss on ignition (LOI) of at least about 2.4 wt %, and the NAP having no abrasive particles. The NAP can include an MC having no abrasive particles with a MOHS scale hardness of at least about 9. The NAP may include CSF coated with a primary coating and a secondary coating on the primary coating. The NAP may have an outer diameter that is at least half of but not greater than an outer diameter of the abrasive article.

Abrasive article

An abrasive article has an abrasive portion and chopped strand fibers (CSF) with enhanced strength and/or fracture of toughness. The CSF may be coated with a thermoplastic having a loss on ignition of at least about 2 wt %. The CSF can have a primary coating and a secondary coating on the primary coating. At least some of the CSF can have a length of at least about 6.3 mm.

Abrasive article reinforced by discontinuous fibers

This invention relates to composite backing materials (e.g., polymer impregnated nonwoven fabrics) and coated abrasive articles that include such composite backing materials. This invention also relates to methods of making and using said composite backing materials and coated abrasive articles. The claimed processes and systems related to the use and manufacturing of coated abrasive articles are improved and cost effective.

Polymer impregnated backing material, abrasive articles incorporating same, and processes of making and using

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

A method includes casting a friction reducing layer on a carrier, and casting an adhesive layer overlying the friction reducing layer to form a multilayer cast film. The method further includes laminating the multilayer cast film to the load bearing substrate with the load bearing substrate to form a composite and shaping the composite. The load bearing substrate is closer to the adhesive layer than to the friction reducing layer.
