3M 7000028143 Trizact 466LA Disc Roll 1.375 in Scalloped

Product Description

The 3M 7000028143 is a Trizact 466LA coated abrasive disc roll designed for fine surface finishing in automotive paint repair and coating correction applications. These discs use 3M microreplication technology, which structures the abrasive mineral in a precise, repeating pattern rather than a random coat. The result is a silicon carbide abrasive surface that cuts consistently from the first disc to the last. Each disc measures 1.375 inches in diameter with a scalloped edge profile. The roll format delivers 500 or more discs per roll, making this a high-volume solution for production shops and detailing operations where throughput and repeatability matter.

These discs are suited for light defect removal and paint correction on automotive panels, including spot repairs and blend work in body shop environments. The silicon carbide mineral is available in very fine micron grades, making them appropriate for the final stages of a multi-step finishing sequence. Color coding by grade helps technicians keep grades organized during multi-step processes and reduces the risk of applying the wrong grade to a finish-stage panel. Automotive body shops and coating repair facilities represent the primary install environment for this product.

Key Features

• Trizact microreplication technology delivers consistent cut rate and predictable finish from start to finish of each disc
• Silicon carbide mineral in very fine micron grades suited for final-stage paint correction
• 1.375 inch diameter with scalloped edge for targeted surface contact in tight repair areas
• Roll format with 500 or more discs per roll supports high-volume production workflows
• Color coded by grade to reduce sequencing errors during multi-grade finishing operations

Compatibility

Designed for use with hook-and-loop backup pads sized to accept 1.375 inch scalloped film discs, commonly used in automotive paint correction and coating repair applications.

Installation Notes

These discs are installed by attaching to a compatible hook-and-loop backup pad on a rotary or orbital tool. Verify that the backup pad diameter and interface type match the disc before use. Work in a clean environment to avoid embedding contamination in the finish surface. Follow the full multi-grade sequence as recommended for the specific paint system being repaired to achieve consistent results.
