Product Details

The 3M Diamond Microfinishing Film Roll 675L comes in a 4 in x 50 ft x 3 in roll with a 20 Micron ASO Keyed Core. This product is sold individually, with one roll per case.

Applications

Perfectly suited for industries requiring high-precision finishing, including aerospace, automotive, and advanced manufacturing. Excels in applications such as thermal spray coating finishing, polishing of hard metals and ceramics, and achieving specific roughness averages (Ra) on challenging substrates.

Usage Tips

For optimal results when applying thermal spray coatings, follow a tailored sequence of abrasive grades based on the substrate and desired Ra. For example, to achieve a Ra of 2.5 to 5 on Tungsten Carbide, start with a 74u grade film, followed by 45u, 30u, and finally 20u. Always consider both the desired Ra and substrate material when selecting your abrasive grade sequence.
