3M Adhesive-Backed/PSA Sanding Disc, 76.2mm Disc Diameter, 320 Grit size - 7100287540

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general sanding, stock removal, surface preparation and intermediate-to-finish sanding across multiple substrates. It combines a blend of aluminium oxide with precision-shaped ceramic grain to deliver controlled cutting performance while allowing dust extraction when used with a compatible support pad and vacuum system.

Features & Benefits

• Precision-shaped ceramic grain for Faster cut rates and longevity
• Net backing enables dust extraction with an extraction system
• Hookit™ loop integration for Rapid disc changes and alignment-free fitting
• Proprietary patterned coating reduces loading and improves finish
• Available in 320+ grade for fine abrasive performance

Applications

• Suitable for scuffing and preparatory sanding of painted surfaces
• Ideal for removing filler and putty prior to final finish
• Used for sanding gelcoat and composite panels in fabrication
• Suitable for surface preparation on metals before assembly
• Can be used for intermediate sanding of whitewood and varnish

How should I store these discs to maintain performance?

Store in the original packaging at 16°C to 26°C and 35 to 50% relative humidity and use stock on a first-in, first-out basis to avoid shortened shelf life.

What backing and attachment method does it use for Rapid changes?

The abrasive is applied to a net backing with integrated loops that mate with a Hookit™ hook-and-loop pad for quick, alignment-free swaps.

Which substrates are compatible with this abrasive formulation?

It is formulated for primer, paint, lacquer, sealer, fillers, gelcoat, composites, whitewood and metals to suit mixed-material manufacturing environments.

What operational benefit does the proprietary coating provide?

The patterned coating is arranged to balance cutting action, finish quality and minimise loading during continuous use.
