3M Wetordry Paper Disc 431Q, 12 in x NH 240 C-weight, 50/Carton, 100 ea/Case

• Adhesive backing provides easy attachment to random orbital sander
• Silicon carbide mineral cuts faster than aluminum oxide and produces a smoother finish
• Strong C-weight paper backing provides durability for either hand or machine sanding
• Versatile disc can be run wet or dry on paint, primer, gel coat, metal, and wood
• Waterproof backing supports wet applications for decreased loading and a faster cut

3M Wetordry Paper Disc 431Q features extra-fast cutting silicon carbide on a strong, waterproof paper backing that gives you superior finishing for both wet and dry applications on a variety of substrates.

Used with water, our 3M™ Wetordry™ discs enable you to rinse areas of the workpiece and the sheet during use to prevent dust and debris from clogging the points of the abrasive and reduce air-borne dust, while producing a faster cut at the same time. These versatile discs are ideal on surfaces that tend to generate a lot of dust, such as paint, primer, and wood; and can also be used dry for finishing metal and gel coats. The adhesive backing provides easy attachment to a random orbital sander.

We chose silicon carbide, a mineral that 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 paint prep and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish.

3M™ Wetordry™ products are backed with a 3M proprietary durable waterproof paper backing that supports both wet and dry applications. Lighter weight than cloth, and smooth rather than textured, paper backing is preferable for lighter applications such as finishing and paint prep. At the same time, many such 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 from the workpiece and the abrasive surface.

3M Wetordry Paper Disc

The 3M Wetordry Paper Disc 431Q offers reliable performance with its adhesive backing, making it easy to attach to a random orbital sander. This feature ensures quick setup and consistent sanding results every time you use it.

Designed for convenience, this model from 3M comes in a pack of 50 discs per carton and 100 discs per case, providing ample supply for both small and large projects.

Extra-Fast Silicon Carbide

These discs use silicon carbide mineral, which cuts faster than aluminum oxide and delivers a smoother finish. This makes them ideal for tasks requiring precision and speed.

Silicon carbide’s sharp edges fracture easily, exposing fresh cutting points that maintain performance. This grade is perfect for paint prep and finishing on wood and metal surfaces.

Strong C-Weight Backing

The 12 inch discs feature a strong C-weight paper backing that provides durability for both hand and machine sanding. This backing supports consistent pressure and wear resistance during use.

This sturdy paper backing is lighter than cloth and smooth, making it suitable for lighter applications like finishing and paint preparation without sacrificing durability.

Versatile Wet Or Dry

These 3M Wetordry discs can be used wet or dry on various surfaces including paint, primer, gel coat, metal, and wood. This versatility allows you to tackle multiple materials with one product.

Using the discs wet helps rinse away dust and debris, reducing clogging and airborne dust, which results in a faster cut and cleaner work environment.

Waterproof Backing Benefits

The waterproof backing supports wet applications, decreasing loading and enabling faster cutting action. This feature extends the disc’s life and improves sanding efficiency.

By using water during sanding, you can rinse the abrasive surface and workpiece, minimizing dust buildup and maintaining a smooth finish on your projects.
