These discs are ideal for a broad range of applications focused primarily on stock removal, and are effective on a wide variety of substrates, including metals, composites, gelcoat, and whitewood. The C-weight paper backing is well suited for sanding applications where edge retention is not a primary requirement. For best results, pair with 3M Elite Random Orbital Sanders.
The 3M Stikit system eliminates the time-consuming task of applying adhesive to the disc backing. These high-quality, 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.
