3M 7100069134 Psa Cloth Disc 20 Inch P100 Grit Ao

Product Description

The 3M 7100069134 is a PSA cloth sanding disc designed for heavy-duty material removal on flat and contoured surfaces. It uses a pressure-sensitive adhesive backing that bonds securely to a backup pad or steel platen, then releases cleanly for fast disc changes. The abrasive mineral is aluminum oxide, paired with a resin bond system that resists heat buildup and extends disc life. The X-weight cloth backing handles aggressive stock removal without tearing or edge breakdown. At 20 inches in diameter and rated P100 grit, this disc suits wide-surface grinding and finishing operations in industrial and fabrication environments.

This disc is suited for both wet and dry sanding applications on metal, wood, composites, and similar surfaces. The 20-inch diameter makes it a fit for large platen sanders and wide-belt-style stationary machines common in production shops, cabinet shops, and metal fabrication facilities. Licensed tradespeople and production-line technicians working high-volume material removal tasks are the typical end users. The PSA mount system speeds up changeover, reducing downtime between abrasive replacements.

Key Features

• Pressure-sensitive adhesive backing bonds to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing resists tearing and edge wear under aggressive cutting loads
• Aluminum oxide abrasive delivers fast cut rate and long service life across multiple surface types
• Resin bond system protects against heat damage, extending disc life in sustained use
• Rated for both wet and dry sanding applications
• 20-inch diameter covers wide surface areas for high-volume production work

Compatibility

Designed for use with backup pads or steel platens accepting 20-inch PSA-mount sanding discs in stationary and production sanding equipment.

Installation Notes

Ensure the backup pad or steel platen surface is clean and free of debris before applying the disc, as contamination will reduce adhesive bond strength. Power down and lock out the sanding machine before mounting or removing any abrasive disc. Press the disc firmly and evenly across the platen to eliminate air pockets. Dispose of worn discs per facility waste procedures and inspect the platen surface regularly for damage that could cause uneven abrasive wear.
