3M™ Wetordry™ PSA Paper Disc 401Q is a silicon carbide disc constructed on a C-weight paper backing. It can be run wet or dry for hand or machine sanding a wide range of substrates. A PSA (pressure sensitive adhesive) backing is available for quick and easy attachment.
Versatile abrasive media can be used wet or dry on a wide range of substrates
Still a favorite among customers for its reduced clogging, long life and great finish, 3M™ Wetordry™ PSA Paper Disc 401Q is a good general use abrasive for hand or mechanical sanding on a wide range of substrates from paint, primer and gel coat to metal and wood.
Sharp Mineral for a Smooth Finish
We chose silicon carbide for this 3M™ product. Silicon carbide is second only to diamond in hardness. This mineral's grain is sharp and narrow and easily fractures. The benefit of this "friability" is that fresh, sharp edges are continuously exposed to the work surface. They cut extra fast and produce a smooth, professional-looking finish. Silicon carbide abrasives are commonly used for low-pressure applications such as paint prep and finishing on wood and metal. While the mineral has a shorter life than aluminum oxide, it produces a superior finish.
3M Proprietary Waterproof Backing
Used dry or with water, our 3M™ Wetordry™ PSA Paper Disc 401Q abrasive enables you to rinse areas of the workpiece and the abrasive during use. This prevents dust and debris from clogging the face of the abrasive and reduces air-borne dust, while cooling and lubricating the workpiece and producing a faster cut. It has the additional advantage of extending abrasive life.
Our 3M™ Wetordry™ PSA Paper Disc 401Q is backed with a 3M-patented durable waterproof paper backing. Lighter weight than cloth and smooth rather than textured, a paper backing works better for lighter applications like finishing and paint prep. At the same time, many of these applications produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. These effects can be minimized by sanding with water to rinse dust away.
PSA Attachment System Is an Option
This abrasive disc comes with a pressure sensitive adhesive (PSA) or regular backing. The PSA backing provides an attachment suitable for high heat and more severe sanding applications.
Recommended Applications
This versatile abrasive disc is ideal for use on surfaces that tend to generate a lot of dust, such as paint and primer, and can also be used dry for finishing metal and gel coats. In the marine industry 401Q abrasive media is used for sanding old finishes, fine feather edging, and surface work.
Engineered to Improve the Process from Beginning to End
We engineered our 3M™ Wetordry™ PSA Paper Disc 401Q abrasive to improve the sanding process from beginning to end. This abrasive makes the sanding processes easier. It's made to cut fast and endure wet sanding so jobs that generate dust don't fatigue it. It's made to generate a great finish. It's another way that 3M helps you get the most from your operations.
