Imported water-abrasive sandpaper without adhesive backing

Imported water-abrasive sandpaper without adhesive backing is selected from imported high-quality grinding sandpaper. It is mainly used with our UNIPOL series grinding and polishing machines. It is cut into circular sandpaper pieces of different diameters according to the different models of polishing machines, and fixed on the grinding and polishing disc with metal clamps to grind the sample. The abrasive grain size classification on the surface of imported water-abrasive sandpaper without adhesive backing is strict, which ensures excellent grinding efficiency, shorter grinding time, and abrasive grains are not easy to fall off, making the sandpaper more wear-resistant and long-lasting. The deformation layer of the sample surface after grinding is more uniform, and there will be no uneven depth. It has excellent water-resistant warping. After the sandpaper is used for water grinding, the curling degree is minimized in the natural state, which ensures the good flatness of the surface when the sample and the abrasive are in contact.
