The premium abrasive used on these Norton 9" x 11" x 320 Grit ProSand Sandpaper Sheets provide superior cut on all surfaces, lasts substantially longer and cuts faster than conventional abrasives, and last 3 times longer than Norton's previous 3X technology. It has an open abrasive grain coated to resist clogging and loading during sanding.
Heat treating toughens the grain allowing it to stay sharp and last longer under extreme pressure, making it the most durable abrasive on the market. Super sharp edges allow grain to remove material faster. The paper's fiber reinforcement and latex saturation give it increased backing weight, offering better grain retention with higher flexibility for easy folding and unfolding without tearing.
The non-pigmented, water based stearate, anti-clog (No-Fil) open coat design provides the best resistance to premature loading during sanding. No color dye is used in the coating process so there is no chance of color transfer to work piece. ProSand Sheets are perfect for sanding paint, drywall, and wood. Pack of 20 sheets. Canada
