Abstract: Coated abrasive material is provided having coated on the adhesive bond a supersize layer which improves grinding and which is stabilized against thermal degradation during use of the abrasive material. This layer comprises an elastomeric material and a sufficient amount of antioxidant to limit oxidative degradation and, in the most preferred embodiment, an active solid, particulate filler. The presence of such a layer on articles manufactured from the coated abrasive material results in a much cooler grinding operation thereby reducing the conditions conducive to metal glazing and resulting in extended coated abrasive product life.
