3M™ Paper Sheet 426U, 150 A-weight, 3-2/3 in x 9 in, Die M220

The silicon carbide abrasive sheets create a smoother finish than aluminum oxide or garnet abrasive products on painted metal and wood substrates. Its resin bond construction provides superior grain retention while the open coat construction, along with the load resistant coating, combine to provide excellent antiloading characteristics. The light A-weight backing provides conformability over contours and into crevasses and corners. The sheet can also be easily cut to fit a hand pad block, inline sanders, or finishing or power sanders. Other applications include general sanding, finishing, blending, surface leveling and prep prior to staining or painting. These versatile sanding sheets contain the ideal abrasive grain type and grades for multi-step finishing processes.

Silicon carbide is a synthetic mineral that is very sharp and commonly used for final finishing in white wood sanding. While it breaks down faster than aluminum oxide, it produces a superior finish.

• Silicon carbide is ideal for general purpose sanding on wood, metal, plastic, dry wall, fiberglass, glass, and ceramic
• Load resistant coating and open coat construction minimize loading
• A-weight paper provides flexibility for finishing contours and angles
• Paper sheet is easily sized according to the task
