ABSTRACT:
An abrasive product comprising abrasive grains bonded together or bonded to at least one major surface of a backing sheet, by a binder formed from a precursor comprising an aminoplast resin having on average at least 1.1 pendant .alpha.,.beta.-unsaturated carbonyl groups per molecule. The binder is formed by curing the precursor at the .alpha.,.beta.-unsaturated site of the carbonyl group, by radiation energy or by heat, in the presence of an appropriate initiator system. The aminoplast resin can also contain pendant amino or hydroxy functional groups, which allow polymerization with condensation curable resins, such as phenolic, melamine, urea, urethane, and furfural resins. Polymerization at the unsaturated site of .alpha.,.beta.-unsaturated carbonyl group can be effected either by radiation energy or by heat, and curing at the sites of the amino or hydroxy functional group can be subsequently effected by heat. The binder of this invention can be used to form the make coat, size coat, both coats, or as a backing treatment of a coated abrasive. The binder material can also be used in fibrous non-woven abrasive products. The binder can be used in embodiments where only a single binder coat is employed.
