Multipurpose Abrasive Designed for Sanding and Finishing
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, our 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. Open coat construction and a load resistant coating help prevent clogging when working with softwoods or paint.
Open-Coat Construction Beats the Dust:
3M NX PSA Paper Discs feature an open coat that allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the disc and hinder sanding ability. With our open coat construction the abrasive grains are spaced slightly apart so that dust and debris have an outlet rather than loading the disc. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. A load-resistant coating further prevents wood dust, paint particles, and other debris from hanging onto and prematurely clogging the surface of the disc, optimizing cut-rate.
