3M™ Microfinishing Film Roll 479L

3M Microfinishing Film Roll 479L is a flexible, fine finishing tool on a polyester film carrier, also capable of fine grinding due to its oriented grain. Ideal for cylindrical parts like rollers and shafts, it ensures consistent, predictable finishes and close tolerances. Suitable for various substrates, including gel coat, soft/hard rubber, composites, fiberglass, metals, and hard-filled rubber. Engineered with micron-graded silicon carbide mineral on polyester film using a resin bond, it offers fast, smooth cutting and a bright finish. Available in different grades for part-specific tailoring, the high-strength polyester backing maintains uniform thickness for critical tolerances. Across industries, from transportation to aerospace, professionals appreciate its precise, uniform cutting action for part integrity and consistency.

• Varying grades of silicon carbide grain
• Robust 5mil polyester (PET) film backing
• Electrostatically aligned coating
