Our durable film construction provides the tear resistance needed for the use of coarse grades in high-production metalworking environments, particularly where edge wear is a concern. The film backing generates a uniform and consistent finish. With a 3M™ Stikit™ backing, this disc is easy to attach to a backup pad (sold separately), and easy to remove. 3M™ Stikit™ Film Disc 375L is suitable for a variety of applications. When the goal is a superior wood finish, the 375L film disc in medium grades conforms well to the contours and rounded edges of challenging work surfaces to deliver a superior finish. Woodworking applications are further enhanced by a load-resistant coating and open coat construction, which reduce clogging and extend the life of the abrasive. For pre- and post-paint finishing, versatility is key, and our 375L film disc in fine grades is designed to deliver a superb uniform finish on plastics and clear coat technologies commonly used in the transportation industry. We designed the 3M™ Stikit™ Film Disc 375L for use with a random orbital sander and our Stikit™ backup pad (sold separately). It comes in a range of grades for various applications from rough sanding to very fine finishing. Our line of Stikit™ discs come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to your Stikit 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 convenient liner prevents the adhesive from becoming dirty and keeps the backing sticky until applied. Film-backed discs have excellent tear-resistant properties and provide a very uniform finish and consistent results with each use. This makes them an excellent option when working on paint, e-coats, primers, gel coats, glass, acrylics and solid surface material, wood topcoats and anywhere else you need the perfect finish every time. We use aluminum oxide abrasive mineral in the manufacture of our 3M™ Stikit™ Film Disc 375L. Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
