3M 7000021269 Wetordry Polishing Paper 281Q 9.0 Micron

Product Description

The 3M 7000021269 is a Wetordry Polishing Paper sheet designed for fine finishing and polishing of contoured surfaces on softer materials. Grade 281Q features aluminum oxide abrasive particles coated on a flexible nonwoven backing, allowing the sheet to conform closely to curved and irregular surfaces. At 9.0 micron grit, this sheet is suited for final-stage polishing passes that remove fine scratches and produce a smooth, consistent surface. It can be used wet or dry, giving technicians flexibility depending on the application and material being worked.

This polishing paper is used in finishing operations involving plastics, aluminum, brass, and copper. Typical applications include surface prep on optical components, instrument housings, decorative metalwork, and precision plastic parts where scratch-free finishes are required. The flexible nonwoven backing makes it especially effective on non-flat geometries where rigid abrasive media would leave uneven results. Each sheet measures 8.5 inches x 11 inches, a standard size compatible with most hand-finishing and block-sanding workflows.

Compatibility

Designed for use on softer non-ferrous materials and plastics including aluminum, brass, copper, and engineered plastic surfaces requiring fine polishing. Part of the 281Q series, also available in 1.0, 2.0, and 3.0 micron grades for progressive finishing sequences.

Installation Notes

No power tools or trade licensing are required for hand use of this abrasive sheet. When used wet, ensure the work surface and runoff are managed appropriately for the material being finished. Keep abrasive sheets away from ferrous metal particles that can contaminate the surface and cause scratching on softer workpieces. Store flat and away from moisture when not in use to preserve abrasive integrity.
