3M 7000139450 Trizact Hook It Film Disc 466LA 6 Inch

Product Description

The 3M 7000139450 is a Trizact Hook It Film Disc in the 466LA series, designed for precision final finishing on automotive clearcoat and painted surfaces. It uses 3M Microreplication technology in which micron-graded silicon carbide is formed into uniform pyramids and evenly bonded to a non-compressible polyester backing. This construction delivers sharp, consistent cutting action that holds up through extended use, producing predictable results with each pass. Licensed HVAC, auto body, and paint finishing technicians rely on this disc for leveling minor surface imperfections without cutting through the clearcoat.

This disc is engineered for automotive paint defect repair work, specifically targeting minor clearcoat imperfections such as dust nibs and light scratches. It fits directly into the 3M Finesse-It two-step paint defect repair process and is well suited for use on mini random orbital sanders. The 6-inch diameter and Hook It backing make mounting and disc changes fast on compatible backing plates. Applications include production body shops, dealership detail departments, and precision refinishing environments.

Key Features

• 3M Microreplication technology forms silicon carbide into uniform pyramids for consistent cut rate
• Stays sharp longer than conventional coated abrasives, reducing disc changes and improving finish consistency
• Non-compressible polyester film backing supports level cutting and minimizes deflection on curved panels
• Hook It attachment system allows fast, tool-free disc changes on compatible orbital backing plates
• Designed for leveling minor clearcoat defects including dust nibs and light surface scratches
• Compatible with the 3M Finesse-It two-step paint defect repair process

Compatibility

Designed for use in the 3M Finesse-It two-step paint defect repair process and compatible with mini random orbital sanders equipped with a 6-inch Hook It backing plate.

Installation Notes

Mount the disc onto a clean, dry 6-inch Hook It backing plate before attaching to the sander. Inspect the backing plate face for debris or worn hooks that could cause uneven disc seating. Operate the sander at manufacturer-recommended speeds for film-backed finishing discs and avoid dwelling in one spot to prevent heat buildup in the clearcoat. This product is intended for use by trained refinishing technicians familiar with automotive paint systems.
