3M 7000028091 Abrasive Disc Roll 5 Inch Psa Non-woven

Product Description

The 3M 7000028091 is a wet-or-dry abrasive disc roll constructed with aluminum oxide particles bonded to a flexible nonwoven backing. Designed for finishing and polishing contoured surfaces, this disc delivers a uniform, consistent finish using precision micron-coated mineral technology. The pressure-sensitive adhesive (PSA) backing allows quick mounting and removal on compatible backup pads. Available in 2.0, 3.0, and 9.0 micron grades, each color-coded for fast identification on the job. Suitable for use on softer materials including plastics, aluminum, brass, and copper. HVAC fabricators, metal finishing techs, and trade professionals working with soft metals will find this disc effective for both wet and dry applications.

This disc roll is suited for finishing and polishing contoured or flat surfaces in light fabrication, metal prep, and surface conditioning work. It is effective on plastics, aluminum, brass, and copper in both residential and commercial trade environments. The nonwoven construction conforms to irregular surfaces, reducing the need for multiple finishing steps and cutting down hand sanding and buffing time. PSA-backed versions in 2.0, 3.0, and 9.0 micron grades are available for progressive finishing sequences.

Key Features

• Aluminum oxide mineral on a flexible nonwoven backing for conformability on contoured surfaces
• PSA backing for fast, secure mounting and removal on compatible pads
• Use wet or dry for versatile application flexibility
• Precision micron-coated mineral delivers a uniform, consistent finish
• Color-coded micron grading (2.0, 3.0, and 9.0 micron) simplifies grade selection
• Shortens hand sanding and buffing time by reducing finishing steps

Compatibility

Designed for use on softer workpiece materials including plastics, aluminum, brass, and copper. Compatible with PSA-style backup pads accepting 5-inch diameter discs. Suitable for wet or dry finishing applications in light metal fabrication and surface conditioning.

Installation Notes

Mount the disc onto a clean, dry PSA-compatible backup pad, ensuring full contact across the adhesive face to prevent edge lifting during use. Inspect the backing pad surface before each disc change and remove any adhesive residue that could cause uneven seating. When used wet, ensure the work area and any power tools are rated for wet-use operation. Dispose of used discs per local regulations if wet with cutting fluids or chemical coolants.
