Joysun Roloc quick change cleaning & strip-it discs are manufactured with the durable, high density non-woven extruded nylon fibers embedded with extra coarse silicon coated abrasives. These products can outperform traditionally coated abrasives and provide aggressive performance, beautiful finish with a long service life. This kind of products will leave behind a thoroughly cleaned surface that ensures excellent adhesion for further processing such as the application of coatings, painting and soldering. Typical applications include removal of surface rust and residue, light weld splatter, dirt, and other contaminants.
