The 3M™ Stikit™ Paper Disc Roll 426U features multiple sanding discs packaged in a roll for convenience and use in high-production environments. Ideal for white wood sanding, sealer sanding, solid surface sanding, or applications where fine finish is critical. The disc itself features a silicon carbide abrasive with a load-resistant coating and open coat construction, which work together to minimize loading.Fast-cutting silicon carbide abrasive creates a smoother finish than aluminum oxide or garnet abrasives, and is effective for finishing on hard woods and solid surfaces. Constructed with A-weight, light paper backing with a pressure-sensitive adhesive (PSA) backing, this disc will flex with the backup pad and flow over contours to help produce consistent finishes. The adhesive holds the disc securely during use and provides quick and easy change out for multi-step sanding and finishing processes. These discs are suited for rotary and random orbital sanders. Applications include general sanding, finishing, blending, surface leveling, and prep prior to staining or painting, and bare wood sanding. Open coat construction means the abrasive grains are spaced so that dust and debris can collect in the spaces rather than loading the disc. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade, for faster results.
