3M 7000000545 Polishing Film Disc 5 Inch Psa

Product Description

The 3M 7000000545 is a 5-inch diameter non-abrasive polishing film disc built on a polyester film backing coated with resilient fibers. Designated as Polishing Film 968M, it features a pressure-sensitive adhesive (PSA) backing for fast, secure mounting to compatible backup pads. The disc functions as a carrier for polishing compounds or slurries rather than as a standalone abrasive, keeping the compound concentrated at the interface between the tool and the work surface. It is suited for precision finishing applications where consistent compound delivery and controlled surface contact are required.

This disc is used in applications where a non-abrasive, fiber-coated carrier is needed to apply or retain polishing compound or slurry on a work piece surface. The soft fiber structure delivers unique finishing characteristics while still maintaining the ability to work through substrate irregularities. Typical applications include optical, metalworking, and precision surface finishing operations. The disc format with PSA backing makes it well-suited for rotary and orbital tool platforms used in production and shop environments.

Key Features

• Non-abrasive fiber surface acts as a durable carrier for polishing compounds and slurries
• Polyester film backing provides dimensional stability during use
• PSA backing allows quick, secure attachment to compatible backup pads
• Soft fiber texture keeps compound at the work piece interface for consistent results
• Available in disc format for use with rotary and orbital finishing tools

Compatibility

Designed for use with 5-inch PSA-compatible backup pads on rotary and orbital finishing tools; intended for use with external polishing compounds or slurries as required by the application.

Installation Notes

This disc is installed by pressing the PSA backing firmly onto a clean, compatible 5-inch backup pad mounted to a rotary or orbital tool. Ensure the backup pad surface is free of debris or residue before attachment to maintain full adhesion. Apply polishing compound or slurry to the disc or work piece as directed by your process requirements. Disc should be replaced when the fiber surface shows wear or when compound retention diminishes.
