3M™ Microfinishing Film Roll 468L, 40 Mic 3MIL, Type E, Unbacksized, Config

The abrasive is resin-bonded and supports flexibility without sacrificing durability and reliable performance under high heat and pressure. To complement the abrasive action, the polyester film backing offers greater tear-resistance than comparable paper products, making it ideal for high-production environments. This roll comes in a range of micron grades for complete multi-step sanding and finishing.

The 3M™ Microfinishing Film Roll 468L features precision, micron-graded silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. Silicon carbide is very sharp and commonly used for low-pressure applications such as paint prep and metal finishing. While it breaks down faster than aluminum oxide, it produces a smoother finish.

• Precision, micron-graded silicon carbide abrasive offers a superior, uniform finish on many substrates
• Durable polyester film backing
• Pressure sensitive adhesive backing allows quick attachment and clean removal
• Open coat construction provides aggressive cut and reduces loading
