A275OP medium grit paper PSA vacuum disc rolls feature a premium, P-grade, heat-treated and toughened aluminum oxide abrasive for superior speed, extended disc life and consistent finishes. They're the best choice for high performance, dry medium grit blending, paint removal and sanding on all materials. Featuring vacuum holes and a water-based, non-pigmented stearate No-Fil® open coating, these discs minimize loading and don't transfer color. The unique fiber reinforced, latex saturated B-weight backing stays flexible while increasing tear strength by 50 to 60 percent, while the pressure sensitive adhesive and linked-disc roll makes application, removal and dispensing quick and easy.
