Use A275 OP 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% 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.
