    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 and also includes a blocked acid catalyst.
