The Scotch Brite™ Clean and Strip Disc is an extra coarse grade, aggressive, open web disc engineered to effectively clean welds, remove rust and strip paint. The open construction and aggressive abrasive properties provide a smooth running wheel that resists loading when removing soft coatings. The non woven disc is a safe alternative to wire brushes, offers a greater surface area, and leaves a finer finish than wire wheels or brushes, which may eliminate the need for subsequent finishing steps. The Scotch Brite™ Clean and Strip Disc uses extra coarse silicon carbide abrasive mineral. 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.
