Finely sand, finish and prep surfaces with PB273 fine grit paper sheets. Armed with a sharp, light-brown, P-grade aluminum oxide abrasive, these paper sheets deliver fast cutting performance and consistent finishes. An open coat design and fully resin-bonded, flexible, latex-saturated B-weight backing increases lifespan and improves performance, while the nonpigmented, water-based stearate coating resists loading and eliminates color transfers and finish contamination. Use these sheets on a wide variety of materials, including fiberglass and composites; aluminum, brass, bronze, titanium and super alloys; hard- and soft-carbon steels; 300 series stainless steels; and hard and soft woods.
