Buffing compound is a material used in polishing operations which must be removed once polishing is complete. Buffing compound consists of a finely divided abrasive mixed with a "vehicle" which is often a paraffin or, in some cases, animal fat and other "fats" depending on their price and availability in a particular region of the world. The "vehicle" performs many functions -
- It holds the abrasive (which would otherwise be a powder) together so that it can be easily handled.
- It acts as a lubricant to help minimize heating of parts due to friction during the buffing operation (more on that later).
- Most "vehicles" (especially paraffin) have a relatively high heat capacity and a high heat of fusion. This, too, contributes to heat moderation during the buffing process.
