- Backing: FSC-certified paper, electrostatic coat
- Bond: resin over resin

Where 180 Grit Fits
Use 180 after 120 or 150 to refine the surface, then finish at 220 or 240. On wood, 180 is a common final step before sealer on many open-grain species.
Who Uses It
Automotive refinishers, collision shops, furniture and cabinet shops and industrial finishing lines use the Sia 8443.7842.0180 on body filler, primer filler, lacquers and paints. The 81-hole pattern pairs with multi-hole 6 inch pads and dust extraction to keep the surface clear while you sand.
Tips for Longer Disc Life
Use light, even pressure and let the abrasive cut. Keep the pad flat to avoid rounding edges, and clean the surface between grits so loose particles from a coarser step do not leave stray scratches. Change the disc as soon as it stops cutting; a worn disc only polishes and builds heat. Store boxes flat in a dry place so the paper stays flat.
