The 3M™ Microfinishing PSA Film Disc 366L features micron-graded aluminum oxide abrasive bonded to a durable polyester film backing to produce a fast cut rate and uniform finish on wood, solid surface composites, plastic, fibreglass, paint prep, coating and corrosion removal, primer, e-coat, or metal.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.
