    摘要: A curable composition includes polyepoxide, high-melting metal particles having a melting point above 300° C., low-melting metallic particles having a melting point of less than or equal to 300° C., and a fluxing curing agent comprising a fluxing curing agent comprising: a hydroxyalkyl-substituted tertiary amine, and at least one diacid compound represented by the formula: HO2C—Z1—CH2CH2CH2—Z2—CO2H wherein Z1 and Z2 independently represent a covalent bond or an aliphatic hydrocarbylene group. The at least one diacid compound comprises at least 50 percent of the total weight of carboxylic acids and anhydrides present in the curable composition. Articles comprising the curable composition, and methods of making the same are also disclosed.

    摘要: Abrasive products comprising abrasive grains bonded together or bonded to a backing by means of a binder compressing an oligomeric aminoplast resin having on average at least one pendant .alpha.,.beta.-unsaturated carbonyl group per oligomeric unit. The oligomeric aminoplast resins polymerize via free radical polymerization at the site of the .alpha.,.beta.-unsaturation. Polymerization is initiated by a source of free radicals. The source of free radicals can be generated by electron beam radiation or by an appropriate curing agent or initiator upon exposure to heat or radiation energy. The coated abrasive of this invention demonstrates improved grinding performance under severe conditions as compared with coated abrasives comprising radiation curable resins heretofore known.

    摘要: 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.
