Use A275OP medium grit paper sheets to produce consistent, exceptional finishes on any surface or coating. Featuring a fiber-reinforced, latex-saturated B-weight backing and non-pigmented, water-based stearate open coating, these sheets resist clogging and provide 50- to 60-percent better resistance to tearing than common papers. Crafted using a premium, heat-treated P-grade aluminum-oxide abrasive, these sheets are ideal for removing moderate material when hand sanding materials that tend to load, such as painted surfaces, plastics and composites. They also work well on fiberglass, aluminum, brass, bronze, titanium and super alloys; hard, soft, and 300-series stainless steels; and hard and soft woods.
