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.
