Crafted using a premium， heat-treated abrasive， ProSand A259PS coarse grit paper sheet cuts faster and longer than ordinary paper and is a great choice for heavy material removal. Pair it with your sanding board/block or sand by hand to remove stock from fiberglass and composites; aluminum， brass， bronze， titanium and super alloys; hard， soft and 300-series stainless steels; and hard and soft woods. Latex-saturated and featuring a heavyweight， fiber-reinforced backing， this highly flexible tear-resistant paper is easy to fold and provides excellent grain retention. The water-based stearate open coating resists clogging and loading and eliminates color transfer during sanding.
