Resists Dust and DebrisIn grades from 80 to 800, 3M™ Stikit™ Gold Paper Disc 216U is engineered for demanding applications that might make other discs entirely ineffective. Aluminum oxide mineral provides a fast cut, durability and performs well on many surfaces.Sandpaper discs cut better and last longer when dust isn't loading the cutting surface of the abrasives. Loading occurs when material clogs the surface of the sanding paper and the abrasive points, which can quickly make the disc ineffective. Open coat construction means the abrasive grains are placed less densely so dust collects in the spaces between the grains and can more easily be evacuated, rather than clogging the cutting edge of the grains. A 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.Flexes Around Curves, ReachesA light and flexible A-weight paper backingflexes around curves and reaches into crevasses and corners. The flatter paper backing makes for a lighter scratch and a smoother finish than cloth, for instance. This handy disc can also be easily cut to fit a hand pad block, inline sanders, or finishing or power sanders.The Speed and Ease of StikitOur 3M™ Stikit™ coated abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to your disc pad is as simple as pressing on a sticker. And because the adhesive is pressure sensitive, the disc can be peeled off of the disc pad just as easily, leaving a clean surface for your next disc. A Stikit disc must be pressed onto a Stikit backup pad (also called a disc pad and sold separately) that is attached to a disc sander, random orbital sander, or stationary disc sander.Paint Prep, Gelcoat, Aluminum and Carbon SteelPaint Prep: Our 3M™ Stikit™ Gold Paper Disc 216U is a good choice for stock removal and finishing on plastic parts and primer.Gelcoat: 3M™ Stikit™ Gold Paper Disc 216U is well-suited for stock removal, medium stock removal and finishing on gelcoat.Gelcoat: Metal Fabrication Applications: Good for finishing on aluminum and carbon steel.3M Science.
