For a consistent finish and exceptional performance on all surfaces and coatings, rely on the A275 OP fine grit paper sheet, which features a heat-treated, P-graded aluminum oxide abrasive. The latex saturated, fiber reinforced backing offers a 50 to 60 percent improvement in tear strength with exceptional flexibility for crack-free folding. This paper sheet is an excellent choice for hand sanding painted surfaces, plastics, composites or any other material that's prone to loading, as the non-pigmented, water-based stearate coating resists both loading and clogging.
