  Proprietary pattern coating reduces loading and refines finish
  Resin pattern bonding maintains abrasive distribution during use

Applications

• Suitable for paint preparation on automotive panels and components
  Ideal for scuffing primers and lacquers before recoating
  Can be used for trimming and finishing composite parts
  Used for Rapid stock removal on metal and softwood components

What backing type supports dust control during sanding?

The open net backing is configured to permit effective dust extraction when used with a compatible backing pad and vacuum system, improving visibility and cleanliness.

How does the abrasive composition affect performance on mixed substrates?

The combination of aluminium oxide and precision-shaped ceramic grain delivers balanced cutting action and surface finish across coatings, fillers, gelcoat, composites and metals.

What attachment method is provided for Rapid disc replacement?

Loops integrated into the net backing mate with a hook-and-loop backing pad, enabling quick swaps without aligning holes or removing a support pad.

Are storage conditions specified to preserve shelf life?

Store in original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in-first-out basis to avoid premature degradation.
