PRODUCT FAQ
-
What is the size of the 3M™ Paper Sheet 405U and how many sheets does it come with?
The sheet size for the 3M™ Paper Sheet 405U is 9 inches x 11 inches, and each case comes with a total of 1000 sheets (packaged as 100 per inner).
-
Can you tell me what A-weight means?
"A-weight" refers to a certain weight classification used for measuring sandpaper grits, bonding systems, backing types and other abrasive products. In this particular product's case, its grit size has been designed using an A-weight classification system.
-
What surfaces can be sanded using the paper sheet?
The versatility of these paper sheets allows them to work well on multiple surfaces including wood, plastic or painted surfaces.
-
How long does each sheet last before needing replacement during use?
The length of time that each sheet lasts depends entirely on how often they are used. However high quality material construction ensures durability even under extensive usage while maintaining constant performance throughout use.
Few shops can do without abrasives in handy sheet form, and 3M™ Paper Sheet 405U is built to be indispensable. A flexible A-weight paper backing provides excellent conformability and silicon carbide abrasive mineral delivers exceptional finishes.
Silicon carbide abrasive sheets create a smoother finish than aluminum oxide products on most substrates. Although it breaks down faster than aluminum oxide, it produces a superior finish. A resin bond construction provides superior grain retention while the open coat construction, along with the load-resistant coating, combine to provide excellent anti-loading characteristics.
These versatile sanding sheets contain the ideal abrasive grain type and grades for multi-step finishing processes.
Paper Backing for Conformability to ContoursThe light A-weight backing provides conformability over contours and into crevices and corners. The sheet can also be easily cut to fit a hand pad block, inline sander, or finishing or power sanders. Other applications include general sanding, finishing, blending, surface leveling, prep prior to staining/painting and scuff sanding between coatings.
Recommended ApplicationsSilicon carbide is a synthetic mineral that is very sharp and commonly used for final finishing in white wood sanding. It is ideal for general purpose sanding on wood, metal, plastic, dry wall, fiberglass, glass and ceramic materials as well as contour blending.
