Armed with a P-grade silicon carbide abrasive, Durite A475 medium grit paper sheets penetrate the hardest of surfaces easily. Featuring a water-based, non-pigmented, no-fil stearate coating, these sheets minimize loading and don’t transfer color to work. The backing is composed of fiber-reinforced latex paper, making these sheets flexible and tear resistant. Use these B-weight sheets for stock removal, painting prep, sealer sanding, paint stripping and more. They work great on gel coats, abrasion-resistant coatings, fiberglass and composites, as well as a variety of metals such as aluminum, titanium, super alloys and steels.
