3M 7100057075 Trizact 466LA 3 Inch Abrasive Disc Roll

Product Description

The 3M 7100057075 is a Trizact 466LA coated abrasive disc roll designed for fine finishing and paint defect correction on automotive surfaces. It uses 3M microreplication technology to form micron-graded silicon carbide particles into uniform pyramidal structures bonded to a 3-mil non-compressible polyester film backing. This construction delivers consistent, controlled cut throughout the life of the disc. The disc roll format is suited for high-volume finishing operations where consistent abrasive performance is critical. Automotive body technicians and refinish professionals are the primary users of this product.

This disc roll is built for use in paint defect repair workflows, particularly two-step processes that require a polish-ready surface after abrading. It performs well on mini random orbital sanders and is appropriate for fine scratch removal, orange peel reduction, and surface preparation prior to polishing. The silicon carbide mineral is available in very fine micron grades, making it suitable for finish-critical automotive refinishing applications where surface quality directly affects final appearance.

Key Features

• Microreplication technology forms silicon carbide into uniform abrasive pyramids for consistent cut and finish
• 3-mil non-compressible polyester film backing provides stability and conforms minimally, reducing uneven stock removal
• Micron-graded silicon carbide mineral in very fine grades for finish-critical work
• Abrasive structures start sharp and maintain cutting performance throughout disc life
• Well suited for use with mini random orbital sanders
• Designed for two-step automotive paint defect repair processes to achieve a polish-ready surface

Compatibility

Designed for use in automotive refinishing applications, particularly with mini random orbital sanders used in two-step paint defect repair processes.

Installation Notes

Installation and use should be performed by automotive refinish technicians familiar with abrasive finishing systems. Ensure the backing pad and sander are clean and free of debris before mounting the disc. Use appropriate eye and respiratory protection when sanding painted surfaces. Follow the equipment manufacturer's recommended speed settings for film-backed abrasive discs to avoid heat buildup or disc failure.
