Abstract
Coated abrasive articles are provided which have at the exposed grinding surface a supersize layer which facilitates grinding. Such a layer comprises a polymeric material and in the most preferred embodiment an active filler. The presence of this layer on the coated abrasive article results in a much cooler grinding operation thus reducing the conditions conducive to metal glazing thereby permitting extended coated abrasive product life.
