Scotch-Brite™ SL Surface Conditioning Belt is a durable, aggressive non-woven belt that balances flexibility with aggressive cutting action. It blends and finishes consistently, often in one step. Balancing Flexibility and Durability Among our surface conditioning belts, the Scotch-Brite™ SL Surface Conditioning Belt falls right in the middle of the spectrum in terms of its durability and flexibility. Balancing both of these elements makes it a good match for medium-duty projects on hard metals. Examples of applications may include intermediate blending, deburring, finishing and cleaning on stainless steel, carbon steel, titanium and nickel alloys. All Scotch-Brite™ SL Surface Conditioning Belts utilize aluminum oxide mineral, but they vary in aggressiveness: Super Duty (SD), Heavy Duty (HD), Coarse (CRS) and Medium (MED). A Responsive Belt The reinforced backing on Scotch-Brite Surface Conditioning Belts offers good flexibility whether working on a file belt or backstand. All belts may be used for “low stretch” applications, because, while flexible, they also stay taut and firm. To engineer the belt, we combine non-woven nylon fibers and mineral with resin. Mixing non-woven nylon fibers, which are springy and responsive, with mineral is an ideal way to add a great finish or remove burrs without gouging or undercutting the workpiece. We also include a woven fabric (scrim) in our conditioning products, which is embedded in the nylon structure to provide additional strength and durability for edge work. Benefits of Aluminum Oxide Mineral Scotch-Brite™ SL Surface Conditioning Belt uses coarse grade aluminum oxide abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing. Surface conditioning belts are used for rapid grinding and finishing on a variety of surfaces. Depending on the material being worked, sanding wheels and discs may clog with debris and quickly become less efficient. Belts continue to sand without clogging, because small grooves in the abrasive belt open as they go around the arc of the drive wheel. Scotch-Brite™ Surface Conditioning Belts present a swift and efficient means to achieve desired finishes.
