3M 01421 Imperial Stikit Film Disc Roll 360L 5 in P500 Grit

The 3M Imperial Stikit Film Disc Roll 360L delivers a fast-cutting, long-lasting abrasive solution for fine finishing on gelcoat, plastics, and polyurethane solid surfaces. Built on a strong film backing — the most durable construction in the 3M Imperial product line — these 5-inch, P500-grit discs are engineered for consistent performance and extended service life.

Key Features:

• Film Backing: Provides superior strength, flexibility, and tear resistance compared to paper-backed alternatives
• P500 Fine Grit: Ideal for fine sanding, scratch refinement, and surface preparation prior to finishing
• Stikit Pressure-Sensitive Adhesive: Disc presses firmly onto any Stikit-compatible backup pad and removes cleanly, leaving no adhesive residue on the pad
• Roll Format: 125 discs per roll with no liners to remove — simply tear off a disc and press onto the backup pad for fast, efficient changeovers
• Aluminum Oxide Abrasive: Sharp, durable mineral that self-fractures to expose fresh cutting edges for consistent cut rate throughout the life of the disc
• Designed for Gelcoat: Optimized for use on gelcoat, plastics, and polyurethane solid surfaces; not recommended for sanding coatings where loading resistance is required
• 5-Inch Diameter, No-Hole (NH): Die 500X; compatible with standard 5-inch Stikit disc backup pads (sold separately)

For best results, use with a 3M Stikit Disc Pad attached to a random orbital or disc sander. These discs are a staple in marine, automotive, and composite finishing workflows where a reliable, fine-grit film disc is required.
