Springy Fibers Adapt to the Part The open-web construction of our Scotch-Brite™ Scuffing Disc combines durability for long life, flexibility for reaching tight areas, and can be used in place of steel wool for conditioning metal surfaces and paint prep. It's a great alternative to steel wool, because it won't rust or splinter during use, thereby prolonging abrasive life and preventing operator discomfort.The buoyant and flexible nylon fibers respond to surface irregularities and quickly abrade the surface without damaging the base material. Hookit™ Backing for Easy Tool Attachment The Hookit backing on Scotch-Brite™ Scuffing Disc has a scrim layer comprised of tiny loops. These loops conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately).The pads are fastened to a random orbital sander and can be removed cleanly and easily and re-used again and again for the extent of the abrasive life. Available in a Variety of Grades Our Scotch-Brite™ Scuffing Disc comes in variety of minerals and grades and is color-coded by grade. These colors are intended to help operators who may use more than one disc reduce the risk for selecting the wrong grade and sanding in error. A very fine (VFN) grade scuffing disc with aluminum oxide mineral performs similar to steel wool grade 0. It is highly conformable with a high cut rate and is great for applications like paint prep on wood finishes. An ultra fine (ULF) grade with silicon carbide performs similar to steel wool grade 00. It is also highly conformable and provides exceptional finishes on wood and metal. The Many Benefits of Open Web Abrasives Nonwoven technology makes our Scotch-Brite™ industrial abrasives unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils, and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity. Gaps in the web allow swarf to escape, so debris does not clog the mineral. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, superior cut performance, and extremely long service life. Scotch-Brite product may enhance productivity while reducing the need for cleaning chemicals and wire brushes. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite abrasives work fast and deliver consistent results, part after part.
