    Extra Product Information

  • The 3M Microfinishing PSA Film Disc 366 features features precision, micron-graded aluminum oxide with an anti-load coating and open coat surface to increase efficiency and product life by minimizing loading
  • The abrasive is resin-bonded and supports disc flexibility without sacrificing durability and reliable performance under high heat and pressure
  • To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear-resistance than comparable paper products, making it ideal for high-production environments
  • And the pressure-sensitive adhesive (PSA) provides easy attachment, holds the disc securely in place during use, and removes cleanly from the backup pad (sold separately)
  • Designed for use with orbital and random orbital sanders, this disc comes in a range of micron grades for complete multi-step sanding and finishing.

    • Product Information

  • Durable polyester film backing provides flexibility for consistent finishing on contoured surfaces
  • Load-resistant coating prevents dust and debris from clogging the disc
  • Open coat construction provides aggressive cut and reduced loading
  • Precision, micron-graded aluminum oxide abrasive offers a fast cut, long life, and uniform finish on many substrates
  • Pressure-sensitive adhesive backing allows quick attachment and clean removal for multi-step finishing processes

    • Suggested Application

  • Ideal for use on plastic, fibreglass, wood, metal or solid-surface composites
