7940 Siaair 6″ Foam Sanding Disc – 2000 Grit Hook & Loop
The 7940 Siaair 6″ Sanding Disc (2000 Grit) is the industry standard for effective surface leveling and paint correction. Ideally suited for the initial stage of finishing after painting, this grit is aggressive enough to efficiently remove orange peel, trapped dust nibs, and paint runs, yet fine enough to leave a scratch pattern that is easily polished out. Whether working on automotive clear coats, lacquered wood, or composite surfaces, the 2000 grit Siaair disc provides the control needed to flatten surfaces without altering the structural integrity of the coating.
Adaptive Foam Backing for Safe Wet Sanding
Engineered with Siaair’s innovative foam cushioning, this disc transforms the sanding process by equalizing pressure across the workspace. This is critical when wet sanding curved panels or complex profiles, as the foam allows the abrasive to hug the surface contours rather than cutting into them. This absorption capability also makes it perfect for wet sanding applications; the foam holds water to lubricate the surface and keep temperatures low, preventing the “pigtails” and uneven scratches often caused by hard-backed abrasives.
Enhanced Durability with Anti-Clog Technology
Productivity is maximized through the 7940’s advanced construction, featuring high-quality aluminum oxide grains and a robust resin-over-resin bonding. This design promotes an open structure that significantly resists clogging, even when sanding soft varnishes or fresh clear coats. The result is a disc that maintains its cutting efficiency far longer than traditional sandpaper, reducing the frequency of disc changes and lowering material costs for high-production body shops and industrial facilities.
