The present invention relates generally to coated abrasive articles, such as coated abrasive film belts having improved strength and durability, as well as methods of making and using said coated abrasive articles.

Coated abrasive film belt

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

An abrasive article includes a backing including first and second major surfaces, an abrasive layer disposed over the first major surface, and a back coat layer disposed over the second major surface. The back coat layer includes a polymeric material and a fabric.
