The 3M™ Hookit™ Gold Paper Disc 216U features an aluminum oxide abrasive constructed on a lightweight paper backing and is suitable for finishing applications with a random orbital sander on wood as well as primer, paint, sealers, topcoats, fibreglass, and plastics. Open coat construction and a load-resistant coating help prevent clogging of the disc to optimize cut and prolong disc life.The 3M Hookit Hook-and-Loop Attachment System makes disc changes fast and easy, meaning the disc can be used again and again for the extent of the abrasive life. Sandpaper discs cut better and last longer when dust isn't loading the cutting surface of the abrasives. Open coat construction means the abrasive grains are placed with space between them to help evacuate sanding dust and avoid clogging the cutting edge of the grains. The load-resistant coating also allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would otherwise clog the disc and hinder sanding ability. Together with the 3M Hookit Backing, these features add up to increased productivity and reduced material consumption.
