Product Information: 3M™ PSA Paper Disc 431Q is a great match for finishing and polishing on paint and metal, and can help remove coatings and corrosion. Its closed coat construction and sharp-cutting silicon carbide mineral render it a good abrasive for soft, brushed finishes. The strong waterproof backing supports both wet and dry applications..

Essential Ingredients
3M™ PSA Paper Disc 431Q features extra-fast cutting silicon carbide on a strong C-weight, waterproof paper backing to provide superior finishing for both wet and dry applications on a variety of substrates, including paint, primer, gel coat, metal, and wood. We engineer this abrasive by adhering silicon carbide to a C-weight backing using a resin bond. Resin is a binding agent that breaks down gradually, helping the abrasive resist heat as it abrades the surface. Silicon carbide is a very hard mineral characterized by sharp points that fracture easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. While the mineral has a shorter life than aluminum oxide, it produces a superior finish. Our 3M™ PSA Paper Disc 431Q is available in a variety of grades, so operators can choose the right grade for their unique project.

Ready to Wash
Featuring a closed coat construction, mineral on 3M™ PSA Paper Disc 431Q covers 100% of the backing. Closed coat abrasives are good for final finishing and polishing, because the dense concentration of mineral means more contact with the workpiece surface area, minimizing the likelihood of missing an area and leaving parts unfinished. While some operators may be concerned about the anti-loading properties of a closed coat abrasive, this paper can be run wet or dry. Using a lubricant like water may help wash away unwanted swarf and debris and reduce discoloration of the part due to heat.

The C-weight backing is one of the heavier backings among paper-backed discs. It's tough, durable and able to withstand repeat sanding. At the same time, it's lighter weight than cloth and smooth rather than textured. Paper backing is preferable for lighter applications such as finishing and paint prep. These applications tend to produce a significant amount of dust, clogging the abrasive points and creating an inferior work environment. Again, the effects can be minimized by sanding with water to rinse dust away from the workpiece and the abrasive surface.

Ease of Use
Made with pressure sensitive adhesive (PSA), this abrasive offers a high-strength adhesive attachment system. Attaching PSA Paper Disc 431Q to your disc pad or hand sander is as simple as pressing on a sticker. The abrasive paper can be peeled off of the chosen holder just as easily, leaving a clean surface for your next abrasive. Our versatile PSA Paper 431Q comes in a variety of forms, from sheets to discs to rolls. Spanning industries and applications, this fast-cutting paper abrasive — with its easy PSA attachment and ability to be run wet or dry — is a versatile and convenient abrasive to have on hand.
