RMC & Riken stearated sandpaper is made by well-chosen grain with special static planting craft, high-quality backing paper, and synthetic resin, anti-static and anti-blocking super coatings on its surface by special techniques. By means of a special process, the uniform distribution and clearance between the grain can effectively discharge the dust from the abrasive surface. The special anti-static and anti-blocking coating can effectively prevent the static. The smooth surface of metal sandpaper grit is good at accelerating the discharge of dust. Soft latex paper brings soft properties to the product, suitable for more grinding methods and fields.
