The Mirka MIR-17-342-220 Carat PSA Linkrol Disc is a premium 5-inch, 220-grit pressure-sensitive adhesive sanding disc designed for dry sanding applications including wood, sealers, paint, and lacquers. Sold in a convenient 100-disc Linkrol (roll) format, these discs are engineered for professional finishing work in automotive refinishing, woodworking, marine, and composite processing environments.

Key Features:

• Abrasive Line: Mirka Carat — a stearate-coated abrasive optimized for dry sanding
• Disc Diameter: 5 inches (17-series)
• Grit: P220 — ideal for fine finishing passes on primer, lacquer, and painted surfaces
• Attachment: PSA (Pressure-Sensitive Adhesive) — quick and secure mounting to foam or rigid backup pads
• Format: Linkrol — 100 discs per roll for fast, efficient disc changes
• Stearate Coating: Zinc-based stearate at 220-grit for reduced loading and clogging on soft materials
• Backing: C-weight paper backing for flexibility and durability during machine sanding
• Bonding: Resin-over-resin construction for superior grain support and long disc life

Mirka Carat discs deliver consistent scratch patterns and a long working lifespan, making them a cost-effective choice for high-production finishing environments. The semi-open grain structure and stearate coating help prevent pill-forming and premature disc glazing, even on soft or heat-sensitive surfaces.
