Norton 66254487395 Durite A475 Medium Grit Abrasive Sheet

Product Description

The NORTON 66254487395 is a medium-grit, P-graded silicon carbide abrasive sheet from the Durite A475 line, designed for demanding material removal and surface prep applications. The abrasive mineral is bonded to a fiber-reinforced latex paper backing that resists tearing and remains flexible during use. A water-based, non-pigmented No-Fil stearate coating minimizes loading and prevents color transfer to the workpiece. These B-weight sheets are built for professionals handling stock removal, sealer sanding, paint stripping, and between-coat sanding on a range of substrates. Each sheet is sold individually and weighs 0.05 pounds.

These sheets are well suited for use on gel coats, abrasion-resistant coatings, fiberglass, and composites. They also perform reliably on metals including aluminum, titanium, super alloys, and steel. The flexible backing allows the sheet to conform to contoured or irregular surfaces, making them practical for automotive, marine, and industrial finishing work where surface consistency is critical. Painting contractors, body technicians, composite fabricators, and metal finishers are the typical end users.

Key Features

• P-graded silicon carbide abrasive penetrates hard surfaces with consistent cut rate
• Fiber-reinforced latex paper backing resists tearing and flexes for contoured surfaces
• Water-based No-Fil stearate coating reduces loading and extends usable sheet life
• Non-pigmented formula prevents color transfer to finished or primed surfaces
• B-weight backing suitable for stock removal, sealer sanding, and paint stripping
• Compatible with gel coats, composites, fiberglass, aluminum, titanium, steel, and super alloys

Compatibility

Designed for use on gel coats, abrasion-resistant coatings, fiberglass, composites, aluminum, titanium, super alloys, and steel substrates in sanding, paint prep, and surface finishing applications.

Installation Notes

Abrasive sheets of this type are installed by hand or mounted to a sanding block or inline sander depending on the application. Ensure the work surface is secure and free of loose debris before beginning. Follow applicable workplace safety guidelines for dust control, including use of respiratory protection when sanding composites, coatings, or metals that produce fine particulate. Replace the sheet when loading is observed or cut rate decreases noticeably.
