Description
Sia 1820 Siamet F PSA Paper Tab Disc is an 1820 siamet disc for metal sanding and finishing work. The 5 inch no-hole PSA format gives fabricators a pressure-sensitive abrasive disc for deburring, rust removal, blending, structuring, and final sanding on compatible shop equipment.
1820 Siamet Disc Benefits
- Zirconia alumina grain supports strong cut on metal preparation and finishing work.
- F-weight paper backing gives the disc a firm base for controlled sanding pressure.
- PSA adhesive back supports quick disc changes on compatible backup pads.
- No-hole format fits non-vacuum sanding setups and simple bench workflows.
- Tab style helps operators lift and remove a used disc from the pad more easily.
Use this abrasive where a metal part needs surface cleanup, edge blending, or finish refinement before coating, assembly, or inspection. Match grit to the material removal step, keep the backup pad clean, and replace loaded or worn discs before heat and debris start marking the work surface.
Common Applications for 1820 Siamet Disc
- Removing rust, discoloration, scale, and shop marks from metal parts.
- Deburring edges after cutting, drilling, machining, or forming.
- Blending weld-adjacent surfaces and touch-up areas.
- Structuring and final sanding before paint, coating, or assembly.
- General manufacturing and fabrication benches using PSA sanding discs.
Compatible Materials and Sanding Notes
- Steel, low-alloy metals, and selected non-ferrous metals when the grit is matched to the job.
- PSA backup pads sized for 5 inch no-hole tab discs.
- Dry sanding workflows where dust control and disc changeover are handled at the station.
- Progressive grit sequences that avoid large jumps between sanding steps.
