Scotch-Brite Roloc Coating Removal Disc features extra coarse silicon carbide abrasive to effectively remove paint and rust from metal surfaces and welds. Together with the conformable, non-woven material, silicon carbide abrasives remove coatings without gouging, undercutting, or damaging the base material, especially on hard surfaces.The open-web material runs cool and resists loading, keeping the abrasives actively cutting for consistent results over the life of the product. Our Scotch-Brite Roloc Coating Removal Disc provides more surface area than wire brushes. It is also safer as there are no wires to fly loose and the hook and loop backing holds the disc securely in place during use. The 3M Roloc TR quick attachment and removal feature also provides fast and easy disc change-out when performing multi-step finishing processes. Scotch-Brite Roloc Coating Removal Disc uses silicon carbide abrasive. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep. While it breaks down faster than aluminum oxide, it produces a superior finish. Scotch-Brite industrial abrasives are a unique surface conditioning product with abrasives incorporated into non-woven nylon or other synthetic fibers. Combining abrasives into the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers. Our 3M Roloc TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly screw onto a 3M Roloc TR disc pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion. The Roloc TR system provides a secure attachment even for heavy-duty applications, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds.
