The ProSand A259PS coarse grit paper sheet, made with a premium heat-treated abrasive, offers superior cutting speed and durability for heavy material removal. It excels on fiberglass, composites, aluminum, brass, bronze, titanium, super alloys, stainless steels, and woods. Its latex-saturated, fiber-reinforced backing enhances flexibility and tear resistance. The water-based stearate open coating resists clogging and prevents color transfer, making it ideal for both sanding blocks and hand use.
