Provided are abrasive articles that include a plurality of layers, in the following order: a backing; an abrasive layer; and a supersize coat. The supersize coat contains a metal salt of a long-chain fatty acid and clay particles dispersed therein. Advantageously, the clay particles enhance the optical clarity of the supersize coat, allowing printed abrasive articles to be made with thicker supersize coatings. The addition of clay was also found to improve cut performance of the abrasive article relative to articles in which the clay particles are absent.

Abrasive articles and related methods

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.

Abrasive article

Abrasive articles comprising abrasive particles and at least one of (a) a reaction product of components comprising a resole phenolic resin and a bisphenol/fornaldehyde resin, (b) a bond system is derived by curing a mixture of a resole phenolic resin and a bisphenol/formaldehyde resin, and/or (c) a bond system comprising polymeric material preparable by combining components comprising a resole phenolic resin and a bisphenol/formaldehyde resin.
