3M™ NX PSA Paper Disc Rolls are ideal for use with hand-held random orbital sanders on a variety of substrates where loading is a concern, and the roll of pressure sensitive adhesive (PSA) discs offers grab-and-go convenience. Featuring aluminum oxide mineral on a durable paper backing (D-weight for grades 40, P60, P80; C-weight for grades P100–P800) with a load-resistant coating, these discs offer aggressive cut and long life. This makes them well suited for extended use in high production operations for general sanding and finishing applications on whitewood, metal, composites, primer, paint, sealers and topcoats. The open coat construction and a load resistant coating help prevent clogging when working with softwoods or paint.
