How many sheets are there per case?
There are approximately 2000 sheets per case of the 3M™ Paper Sheet, providing you with plenty to use in your projects.
What types of surfaces can be sanded using this paper sheet?
This paper sheet is versatile and works on wood, paint, metal, and plastic.
Can these sheets be cut down to smaller sizes if needed?
Yes! These paper sheets are flexible enough to be cut down into any shape or size that may better suit your project's needs.
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 Contours
The 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 Applications
Silicon 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.
