3M™ Paper Sheet 405N is a general purpose abrasive sanding paper constructed on a light, A-weight backing and features an open coating of abrasive grain to help prevent loading. The aluminum oxide abrasive and light backing make this paper an ideal product for sanding applications like paint prep, white wood sanding, sealer sanding, and solid surface finishing.
Flexible Hand Sanding
3M™ Paper Sheet 405N is best suited for light sanding and finishing thanks to its flexibility and fast cutting abrasive material. Its light, A-weight paper backing provides smooth operation even in small contours and can be easily cut and folded to fit any work piece or hand tool. The abrasive side features a closed coat for fine finishing and a distinct grey color helps to easily differentiate it from other grits and grains.
Silicon Carbide Abrasive
This paper sheet primarily uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as cleaning and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish.
Open Coat Resists Loading
Sanding paper cuts better and lasts longer when dust isn’t clogging the cutting surface of the abrasives. Open coat construction means the abrasive grains are placed with space between them to help evacuate sawdust and other sanding debris and avoid clogging the cutting edge of the grains. This allows the sheet to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the grain and hinder sanding ability. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. All of this adds up to increased productivity and reduced material consumption.
