Norton ProSand P180B Sand Paper Sheet. With a water-based, non-pigmented stearate coating that offers an open coat with excellent resistance to loading and clogging, this ProSand paper sheet is made without color dye to prevent color transfer. The premium, heat-treated abrasive cuts faster and lasts longer than 3X technology, and the latex saturation, fiber reinforcement and increased weight offer tear resistance and grain retention while still being flexible enough to fold. Use this sandpaper to finish and prepare the surfaces of hard and soft carbon steels, soft metals, titanium, super alloys, hard and soft woods, fiberglass, and composites.
