The present disclosure relates to saturated or primed abrasive article constructions 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. 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.
