3M 7000044993 Psa Microfinishing Film Roll 180 Micron

Product Description

The 3M 7000044993 is a precision PSA (pressure-sensitive adhesive) microfinishing film roll designed for controlled, micron-graded stock removal and surface finishing. Built on a durable polyester film backing, it delivers consistent cut and finish across the full length of the roll. The load-resistant coating helps prevent glazing and extend usable roll life during production finishing operations. At 180 micron grade, this roll targets aggressive material removal while maintaining dimensional control. It measures 4.5 inches wide by 150 feet long and fits a 3-inch core. Machinists, toolroom technicians, and production finishing operators are the primary users.

This roll is suited for flat lapping, cylindrical grinding, and precision surface finishing applications where consistent micron-grade abrasion is required. The PSA backing allows direct mounting to rigid or semi-rigid platens and backup pads without additional adhesives. It is commonly used on metals, composites, and engineered plastics in production or job-shop environments. The film backing resists tearing and maintains flatness under load, making it appropriate for tight-tolerance finishing work on machine components, molds, and tooling surfaces.

Key Features

• 180 micron abrasive grade for aggressive material removal with controlled finish
• PSA backing for direct platen or backup pad mounting
• Durable polyester film backing resists tearing and maintains flatness under load
• Load-resistant coating reduces glazing and extends roll service life
• 4.5 inches x 150 ft roll length reduces changeover frequency in production settings
• 3-inch core fits standard production roll-finishing equipment

Compatibility

Designed for use with standard roll-finishing equipment and platen systems that accept 3-inch core PSA abrasive film rolls. Confirm equipment core size and platen width before installation.

Installation Notes

Installation is performed by production finishing technicians or toolroom machinists. Power down and de-energize all finishing equipment before loading a new roll. Ensure the platen or backup surface is clean and free of debris before applying the PSA film to prevent voids or bubbles that affect finish consistency. Follow the equipment manufacturer's feed rate and pressure guidelines for film abrasives.
