Chemico Grinding Paste has a lithium grease base, specifically formulated and manufactured solely for Chemico Sales & Overseas Ltd. 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 five grades enable the optimum Chemico Grinding Paste for each operation to be selected for the most efficient grinding.

- Avoid contact of the grinding paste with the valve stem and guide
- Grind the valve in the normal manner until a uniform seat of the desired appearance is obtained

- When a satisfactory seat has been obtained, clean off well and degrease with a suitable solvent such as paraffin before valve reassembly
