Premium 7940 Siaair 5″ Foam-Backed Sanding Discs (2000 Grit)

The 7940 Siaair 5″ Sanding Disc is the industry benchmark for ultra-fine finishing and precision surface refinement. Specifically engineered for the most delicate stages of the polishing process, this 2000 Grit abrasive ensures a flawless transition from sanding to a high-gloss shine. Unlike traditional flat abrasives, the Siaair system is designed to handle the complexities of modern coatings with ease and consistency.

Pressure-Equalizing Foam Technology

The standout feature of the 7940 Siaair is its integrated foam-backed construction. This cushioning layer provides a significant advantage for high-end detailing and refinishing:

• Contour Adaptation: The foam backing allows the disc to “hug” curves, swage lines, and complex profiles, ensuring an even finish on non-flat surfaces.

• Preventing Burn-Through: By distributing pressure evenly across the face of the disc, it virtually eliminates the risk of sanding through clear coats or creating unsightly pressure marks.

• Enhanced Surface Contact: The flexible structure ensures that the abrasive grains maintain constant contact with the workpiece, resulting in a more uniform scratch pattern.

Versatile Wet & Dry Performance

Built to withstand the rigors of professional environments, the 7940 Siaair is fully optimized for both wet and dry applications.

• Anti-Clogging Design: A specialized coating process prevents the buildup of sanding dust and slurry, allowing the disc to cut effectively for longer periods.

• High-Quality Aluminum Oxide: The premium abrasive grains deliver a consistent, predictable cut rate, ensuring that the surface is perfectly prepped for final compounding and polishing.

• Cost Efficiency: Exceptional durability means fewer disc changes per project, lowering your total consumable overhead while maintaining high-speed productivity.
