Sunmight Film PSA Sanding Discs are a premium product with strong and even film backing that allows for better surface finish and longer working life.
Sunmight Film features a polyester backing that is strong and durable; it does not tear or crack easily and perfect for sanding edges, corners and irregular shapes and may also be used wet or dry.
With its uniform mineral coating on a perfectly even surface, Sunmight Film performs better than traditional paper abrasives. The even film surface results in an outstanding finish without deep scratch marks. Additionally, special resin over resin adhesion technology reduces shelling (grit shedding) problems and provides longer working life.
