3M 7000000289 Wetordry Polishing Paper 481Q 30 Micron

Product Description

The 3M 7000000289 is a silicon carbide abrasive polishing paper designed for finishing and polishing contoured surfaces on softer materials. Sold as the 481Q grade in 30.0 micron grit, it features silicon carbide mineral coated onto a flexible nonwoven backing that conforms easily to curved and irregular profiles. The sheet measures 8.5 inches by 11 inches and can be used wet or dry, giving technicians the flexibility to match the polishing method to the material and finish requirement. This product is used in precision surface finishing applications across trades and light manufacturing.

This polishing paper is suited for fine finishing work on softer substrates including plastics, composites, and soft metals. The flexible nonwoven backing allows it to follow contoured surfaces without bridging or tearing, making it a practical choice for detail work and final-stage polishing. It is available in 15.0 and 30.0 micron grades, allowing the user to select the cut appropriate to the surface condition and desired finish level.

Installation Notes

This product is a hand-applied abrasive sheet and does not require power tools or mechanical fastening. When used wet, ensure the work surface and sheet are adequately lubricated to reduce loading and extend sheet life. Dispose of used abrasive sheets in accordance with local waste disposal guidelines, particularly when polishing materials that generate fine particulate. Personal protective equipment including eye protection and gloves is recommended during use.
