A durable aluminum oxide Stikit™ disc roll constructed on an A Weight light paper backing. The open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade and a special loading resistant coating makes this disc a good choice when loading is a problem. This disc is slightly more aggressive than 3M™ Stikit™ Gold Paper Disc Roll 214U. Stikit™ Gold Paper Disc Roll 216U is designed for convenience, combining open coat aluminum oxide discs with a handy adhesive backing ready for quick and easy attachment to a 3M™ Stikit™ Disc Pad on a random orbital sander (both sold separately). The disc roll makes the discs easy to grab while eliminating the use of disc liners. Discs are made of long-lasting aluminum oxide abrasive grains on a light A Weight paper backing suitable for lightweight sanding and finishing. The open coat and load-resistant coating help prevent loading for a longer service life, and make 216U discs well-suited for general sanding and finishing applications on a variety of substrates, including paint, primer, wood, metal, plastic, and composites, including Fibreglass. 3M™ Stikit Discs is designed to handle a wide range of sanding and finishing needs. These high-quality, coated abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so they conveniently press on to the backup pad, and remove cleanly, leaving an uncontaminated surface for the next disc.
