Silicon Carbide Sandblasting Abrasive, 150 Grit - 50 lb. Bag

Silicon carbide: is preferred for flat lapping of materials such as glass, crystal, metals and ceramics. It is commonly used for blasting metals, because it leaves behind a polishing effect. SC cuts very quickly, faster than AO in pressure blast applications, because it has a sharper structure. It does not, however, recycle as well as AO. SC's advantages include its reflective properties, polishing ability of metals, and speed of etch on glass. Proper precautions need to be taken when exposed to finer particulate. 50lb. Bag
