3M™ Wetordry™ Paper Sheet 413Q, 35444, 400 Grit, 27 in x 27 in, 250 sheets per case

The 3M™ Wetordry™ Abrasive Sheet 413Q is best suited for metal sanding and finishing thanks to its versatility and fast cutting abrasive material. Its flexible, A-weight paper backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing.

This paper primarily uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard but 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 cleaning and finishing on paint and metal.

This paper also uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft surfaces. This also allows for faster sanding and a higher cut rate. The waterproof coating enables the user to rinse areas of the workpiece and the paper during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time.

• Silicon carbide mineral provides an aggressive cut and a consistent, fine finish
• Light, A-weight paper backing offers excellent flexibility in hands-on applications
• Resin bonding resists deterioration from heat, extending the life of the abrasive cloth
• Waterproof material allows for easy debris removal
• Can be easily cut and folded to fit any hand tool or work piece crevice
