Product Overview

Sunmight 5" Film Solid PSA (Sticky‑Back) Sanding Discs deliver a premium surface finish with a durable polyester film backing engineered for longer life, consistent cutting, and exceptional edge durability. These discs are ideal for automotive refinishing, marine repair, woodworking, solid surface fabrication, and industrial finishing applications.

Sunmight’s advanced film technology provides a perfectly even surface with a uniform mineral coating, producing a smoother finish than traditional paper abrasives. The film backing resists tearing and cracking, making it excellent for sanding edges, corners, contours, and irregular shapes. Discs may be used wet or dry.

The PSA (pressure‑sensitive adhesive) backing ensures a secure bond to vinyl‑face pads and delivers fast disc changes with no slippage. Designed for use on any 5" random orbital sander equipped with a PSA backup pad.

Available in 80 to 2,000 grit. Sold 100 discs per box.
