Abstract: The present invention provides a flexible abrasive product comprised of an open cell foam backing, a foraminous barrier coating and a shaped foraminous abrasive coating.

Abstract: Endless coated abrasive articles having a splice. In general, the coated abrasive articles comprise a backing having abrasive grains bonded thereto by one or more layers of binder. This invention also provides a method of making the splice by using radiation curable adhesives, e.g., acrylated urethanes, and radiation energy to cure the adhesives. The radiation curable splice adhesive essentially solvent-free. Consequently, the time required for the solvent to flash off is eliminated and solvent removal is no longer an environmental concern. By utilizing a source of radiation energy, the splice adhesive can be solidified in less than one minute. Because the splice adhesive is fully solidified, coated abrasive belts can be packaged immediately after the splice is formed.

Abstract: An abrasive article is presented which includes a backing having a front and back surface, and an abrasive coating bonded to the front surface of the backing. The abrasive coating comprises a homogeneous mixture of a plurality of abrasive particles, a binder and a grinding aid. The binder serves to bond the abrasive coating to the backing and the grinding aid comprises at least 1% by weight of the abrasive coating, but not more than 50% by weight. It is preferred that the abrasive coating consists essentially of a plurality of precisely shaped abrasive composites. Methods of making and using the abrasive articles are also presented.

Abstract: A coated abrasive article comprising a backing bearing on at least one major surface thereof abrasive composites comprising a plurality of abrasive grains dispersed in a binder. The binder serves as a medium for dispersing abrasive grains, and it may also bond the abrasive composites to the backing. The abrasive composites have a predetermined shape, e.g., pyramidal. The dimensions of a given shape can be made substantially uniform. Furthermore, the composites are disposed in a predetermined array. The predetermined array can exhibit some degree of repetitiveness. The repeating pattern of a predetermined array can be in linear form or in the form of a matrix.

Abstract: An abrasive product comprising abrasive grains bonded to at least one major surface of a backing sheet by a binder formed from a blend comprising radiation curable monomer and a thermally curable resinous material. The radiation curable monomer can be selected from the group consisting of isocyanurate derivatives having at least one terminal or pendant acrylate group, isocyanate derivatives having at least one terminal or pendant acrylate group, and multifunctional acrylate monomers. The thermally curable resinous material is preferably a member selected from the group consisting of phenolic resins, urea-formaldehyde resins, melamine-formaldehyde resins, and epoxy resins. The binder can be used to form the make coat, size coat, both make and size coats, or as a backing treatment for a coated abrasive product. The binder can also be used in fibrous nonwoven abrasive products. The binder can also be used in embodiments where only a single-coat binder is employed.
