Chemico Grinding Paste (2.5kg) is a silicon carbide and lithium grease grinding compound available in 3 grades : - Fine (220 grit) - Medium (120 grit) - Coarse (80 grit) Chemico Grinding Paste has a lithium grease base, specifically formulated and UK manufactured.  The high-viscosity, high-temperature lubricant provides inherent shear stability, that is the lubricant remains in place during the grinding operation for the most efficient grinding together with inherent corrosion protection and good sealing properties.  Silicon carbide is one of the hardest abrasives known and the particles are especially sharp.  Moreover they are brittle and tend to break up into smaller particles that still retain their sharpness and so continue to work efficiently.  Silicon Carbide is milled to provide the graded particles in each type of grinding compound. The four grades enable the optimum Chemico Grinding Paste for each operation to be selected for the most efficient grinding. Uses General Engineering. Tool making.
