Abstract
An abrasive article is provided which comprises a plurality of layers in the following order: a backing; an abrasive layer; a primer layer comprising clay particles, wherein the clay particles are agglomerated and form a layer; and a supersize coat comprising a metal salt of a long-chain fatty acid. The addition of the aforementioned primer layer can significantly reduce loading of swarf and improve both the cut and expected lifetime of the abrasive article.
