Description
Sia 1820 Siamet F PSA Tab Disc is an 1820 siamet disc for metal finishing work that needs steady cutting, clean scratch patterns, and pressure-sensitive mounting. The no-hole, six inch tab format fits PSA backup pads used in fabrication, repair, and finishing cells.
1820 siamet disc Benefits
- Zirconia alumina grain helps maintain cut on steel and non-ferrous metal surfaces.
- F-weight paper backing gives the disc a firm, stable feel for controlled sanding.
- Closed coat, resin over resin bonding supports dependable grain retention during metal work.
- Cooling additive helps manage heat during heavier sanding passes.
- PSA tab construction supports quick removal when changing grits or replacing spent discs.
This disc is a practical choice for shops that move between rust removal, surface treatment, deburring, blending, structuring, and final sanding. It is best matched to metal applications where the operator needs a firm paper-backed abrasive that can handle direct contact pressure without a hook-and-loop interface. The tab helps technicians lift the disc from the backup pad at changeover, which is useful when several grits are staged at one bench.
Common Applications for 1820 siamet disc
