The A290 coarse grit paper PSA disc roll features P-graded aluminum oxide for fast cutting and a consistent finish that lasts. It’s ideal for blending, stripping, and sanding aluminum, composites, wood, carbon steels, fiberglass, and soft metals like aluminum. The flexible, fiber-reinforced C-weight backing resists tearing, while the linked disc roll and pressure-sensitive adhesive ensure easy application and removal. The No-Fil coating, open coat, and water-based stearate minimize loading.
