Systems and methods include providing a coated abrasive article with an enhanced anti-loading composition in a supersize coat. The anti-loading composition includes a mixture of a metal stearate, at least one performance component, and a polymeric binder composition.

Coated abrasives having an improved supersize coating

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 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 glass mat includes an assembly of glass fibers, a binder composition and an asphaltic coating. The binder composition includes an organic resin and an adhesion promoter. The glass mat has an at least 2% increase in tear strength as measured using the methods specified in ASTM D3462, compared to an asphaltic coated glass mat having a binder composition without the adhesion promoter. Further provided is an asphalt roofing product including the glass mat and a method of increasing tear strength in an asphalt roofing product.

Glass mat for roofing products

A surface-treating article includes an organic matrix substantially engulfed by a binder that includes a reaction product of a blocked polyurethane prepolymer and a mixture of aromatic amines. The aromatic amines include polymethylene polyaniline having a functionality equal to or greater than 4.

Smear-free nonwoven composite abrasives

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

A reinforcing web has multiple fibers joined together with a binder. At least some of the fibers have foldable portions, wherein the foldable portions have substantially less binder thereon to increase flexure to fold the web. A method of making the reinforcing web includes, applying a binder on the web, and removing some or all of the binder from a foldable portion of the web prior to curing the binder that remains on the web.

Foldable reinforcing web

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 article includes a fibrous substrate, a binder disposed on the fibrous substrate, and abrasive grains in contact with the binder. The binder includes an imide cross-linked urethane derived from a blocked isocyanate component and an anhydride component.

Imide cross-linked binders for abrasive articles

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

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.

Abrasive particle and method of forming same

An aqueous polymer binder composition adapted for the manufacture of abrasive articles, such as coated abrasive articles, comprising at least one resin containing at least two azetidinium groups and at least one saccharide. The aqueous composition is formaldehyde-free and can further comprise proteins, starch grafted acrylic styrene, co-cross-linking agents, rheology modifiers, fillers, and hydrophobizing agents.
