[Product Description]: For fine, high-precision topcoat. Micron-grade high-quality minerals, resin binder, reusable performance. Uniform size and precision, resistant to water, oil, and most solvents.
It is made of regular aluminum oxide abrasive grains in micron units bonded on a film substrate with uniform thickness. Therefore, a uniform processing surface can be obtained. It is used for: electronic precision grinding, rollers, camshafts, crankshafts, magnetic heads, experimental metallographic sample manufacturing, compounds (non-semiconductor), optical fiber, optical connectors, LCD panels, gemstones, hard disks, micro motors, molds and other precision grinding. Currently, 0.05/0.3/0.5/1/3/5/9/12/30MIC and other particle sizes are available
