A coated abrasive article comprises a backing, a first binder (i.e., a make coat) on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acrylate component, and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated porous cloth material.

Coated abrasive article and method of making same

A coated article comprising a backing and a binder is disclosed. The binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, a polyfunctional acrylate component, and a curing agent for crosslinking the epoxy resin. The binder precursor is cured to provide a crosslinked coating. The invention also relates to a method of producing such coated articles and a surface-treated porous cloth material.

Surface treated backings for coated abrasive articles

Precisely shaped abrasive composites are disclosed. The abrasive composites comprise from 20 to 75 percent by weight at a plurality of abrasive grits and a binder.

Precisely shaped abrasive composite

Precisely shaped composites and methods for making these composites are disclosed. The method of this invention comprises the steps of:

Method of making a coated abrasive article comprising precisely shaped

Precisely shaped particles and method of making the same

Abrasive articles comprising precisely shaped particles are disclosed. The particles are bonded together to form a shaped mass, e.g., a wheel; alternatively, the particles can be bonded to a backing to form a coated abrasive article; or the particles can be bonded into a fibrous, nonwoven substrate to form a non-woven abrasive article.

Abrasive articles comprising precisely shaped particles

A tear resistant coated abrasive article comprises a backing which comprises a film having at least five layers situated one on the other in a parallel array. The layers occur essentially randomly in the array and are individually selected from a stiff polyester or copolyester and a ductile polymeric material. An abrasive layer is on a surface of the backing.

Tear resistant coated abrasive article

A tear resistant coated abrasive article comprises a backing which comprises a film having at least three layers situated one on the other in a parallel array. The layers occur essentially randomly in the array and are individually selected from a stiff polyester or copolyester and a ductile sebacic acid based copolyester. An abrasive layer is on a surface of the backing.

Coated abrasive article having a tear resistant backing

Surface-finishing articles comprising a lofty, nonwoven, three-dimensional web of polyester fibers coated with a phenol-formaldehyde resin binder. The polyester fibers are exposed to UV radiation prior to being coated with the resin binder A pretreatment of hydrogen peroxide may also be employed

Nonwoven polyester articles and method of making same

A primed polymeric article is provided. The article comprises a polymeric substrate having graft polymerized thereon at least one organic nucleophilic graft-polymerizable monomer or salt thereof which is capable of accelerating the cure of a cyanoacrylate adhesive. The invention also provides an article wherein the primed polymeric article is adhered to a substrate with a cyanoacrylate adhesive and a method for adhering a polymeric first substrate to a second substrate with a cyanoacrylate adhesive.
