The present disclosure relates generally to coated abrasive articles that include a tribological performance enhancing composition in a make coat, a size coat, a supersize coat, or combinations thereof, as well as methods of making coated abrasive articles. The present disclosure also relates to coated abrasive articles including a supersize coating comprising a sulfide scavenging composition and/or a crosslinked zinc acrylic binder, as well as methods for making and using such abrasive articles. The present disclosure also relates generally to abrasive articles that include aggregates having an anti-wear composition or grinding aid disposed on or within the aggregates.

Coated abrasives having a performance enhancing composition

The present disclosure relates to abrasive buffing articles ('abrasive buffs') and methods of making the same. The abrasive buffs include a substrate, such as a fabric, that has been impregnated with an abrasive polymeric composition that includes abrasive particles, such as primary abrasive particles and/or abrasive aggregates, such as spray dried abrasive aggregates. The abrasive buffs are flexible and capable of conforming to and effectively abrading, polishing, and buffing workpieces possessing a complex geometry.

Abrasive buffing articles

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.

Coated abrasives having aggregates

The present disclosure relates to abrasive articles that include abrasive aggregates of silicon carbide with a vitrified bond, and methods of making and using such abrasive articles and abrasive aggregates. In particular, the abrasive aggregates can possess a combination of beneficial properties and comprise a vitreous binder composition having a specific composition, sintering temperature, glass transition temperature, or a combination thereof.

Abrasive articles including aggregates of silicon carbide in a vitrified bond

A coated abrasive product includes 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, wherein the abrasive aggregates are dispersed within a polymer resin coating, and wherein the coated abrasive product is capable of superfinishing a metal surface having an initial Ra in the range of about 1.5 micro inches to about 12.5 micro inches prior to application of the coated abrasive product and after application the surface has an Ra of less than 1.0 micro inch.

Abrasive products and methods for finishing hard surfaces

The present disclosure relates to abrasive aggregates comprised of abrasive particles in a vitreous binder composition, and methods of making and using such abrasive aggregates, including in abrasive articles. The abrasive aggregates can include modifier particles. The abrasive aggregates can include a layer of outer particles on at least a portion of the outer surface of the abrasive aggregate.

Aggregates of diamond with vitrified bond

A coated abrasive product includes 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 sulfosuccinate, and a crosslinking, wherein the abrasive aggregates are dispersed within a polymer resin coating comprising a mixture of copolyester resin. The coated abrasive product is capable of finishing coated surfaces and repairing defects in coated surfaces, including surfaces coated with automotive primers, paints, clear coats, and combinations thereof.

Abrasive products and methods for finishing coated surfaces

An engineered coated abrasive product having a three dimensional pattern of abrasive structures formed by embossing an abrasive slurry formulation that was first surface coated with a functional powder, wherein the abrasive slurry includes 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. The coated abrasive product is capable of finishing and repairing defects in surfaces, including coated surfaces.

Abrasive products and methods for finishing surfaces

Abrasive aggregates and fixed abrasive articles comprising formaldehyde-free polymer binder and a plurality of abrasive grains are provided that are particularly suitable for machining operations, in which abrasion is carried out to remove material and improve surface quality. Certain embodiments combine an abrasive grain, which can be in the form of microparticles, and a formaldehyde-free polymer binder, which can be in the form of a polymer resin and cross-linking agent. Optionally, the abrasive aggregate can contain a secondary cross-linking agent, or a functional filler, such as a grinding aid.

Coated abrasive aggregates and products containg same

A coated abrasive product including 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, wherein the abrasive aggregates are dispersed within a polymer resin coating, and wherein the coated abrasive product is capable of polishing an optical component, including ophthalmic lenses without the need to apply an abrasive slurry.

Abrasive products and methods for fine polishing of ophthalmic lenses

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.

An abrasive article comprising an abrasive particle including a core comprising a compressible material, an intermediate layer comprising a binder material overlying an exterior surface of the core, and an outer layer comprising abrasive grains overlying the intermediate layer.
