3M Adhesive-Backed/PSA Sanding Disc, 203mm Disc Diameter, 80 Grit size - 7100284518

This adhesive-backed/PSA sanding disc is a coarse 80 grit abrasive designed for heavy material removal in industrial sanding systems. It combines precision-shaped mineral with a flexible cotton cloth support to perform on metals, woods and composite substrates while being compatible with hook-and-loop and PSA attachment workflows in production or maintenance environments.

Features & Benefits

• Precision-shaped grain delivers fast cutting and extended service life
• Open coat construction reduces loading, maintaining cut rate
• Anti-static treatment neutralises charged swarf for cleaner operation
• Cotton cloth backing provides wear resistance with conformability
• Multi-hole extraction compatibility improves dust collection efficiency

Applications

• Suitable for coarse stock removal on metal fabrications
• Ideal for surface preparation before coating in automotive workflows
• Used for sanding hardwood and softwood in production lines
• Can be used for composite and gelcoat smoothing in manufacturing
• used with vacuum-equipped random orbital sanders for dust control

How does the abrasive maintain performance as it wears?

The grain fractures to form new Sharp edges, preserving cutting Ability and consistent removal rates.

What dust control provision improves productivity?

A multi-hole extraction pattern works with a vacuum back-up pad to avoid loading and keep throughput high.

Which attachment methods will accept this disc?

It is supplied with a pressure-sensitive adhesive backing compatible with PSA hook and loop replacement systems and suitable for adhesive-backed mounting.

What backing material supports repeated industrial use?

A J-weight cotton cloth backing offers a balance of flexibility and wear resistance for demanding sanding tasks.
