Abstract: The present disclosure relates to an abrasive article construction containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. In one aspect, the present disclosure provides an abrasive article including a backing with a first major surface and an opposing second major surface, an abrasive layer bonded to at least a portion of the first major surface, with the abrasive layer comprising abrasive particles retained in a make coat. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer.

Abstract: The present disclosure provides a polymer bond abrasive article formed of a continuous photocured polymer matrix having abrasive particles retained therein. The photocured polymer matrix includes at least one of an optical brightener or a light absorber, and the polymer bond abrasive article has a three-dimensional shape. An abrasive tool is also provided, including the abrasive article affixed to a shaft or a pad. Further, a method of making the polymer bond abrasive article is provided, including a) obtaining a photocurable composition liquid dispersion; b) selectively curing a portion of the photocurable composition; and repeating steps a) and b) to form the polymer bond abrasive article. The dispersion contains at least one photocurable component; abrasive particles; a photoinitiator; and at least one of an optical brightener or a light absorber.
