The inventive abrasive article reduces the grinding energy required while improving abrading efficiency in some cases.
Claims14
A coated abrasive article comprising a substrate having a plurality of abrasive particles adherently bonded thereto by a binding material, and a peripheral coating layer comprising a non-aqueous thermoset binder and an inorganic metal phosphate salt devoid of hydrogen selected from the group consisting of an alkali metal orthophosphate salt and an alkaline earth metal orthophosphate salt, wherein the thermoset binder forms a substantially continuous medium by which the inorganic metal phosphate salt is attached.
A coated abrasive article comprising a substrate having a plurality of abrasive particles adherently bonded thereto by a binding material, and a peripheral coating layer comprising an anhydrous thermoset binder system and an inorganic metal phosphate salt devoid of hydrogen selected from the group consisting of alkali metal orthophosphate salt and an alkaline earth metal orthophosphate salt, wherein the binder system is cured at a temperature of at least about 100.degree. C. for a time sufficient to form the peripheral coating layer.
