Metal working oils have many different uses in many different industries. They are used as lubricants in the metalworking, cement, ceramic and plastic industries. They are also being used as additives in other types of fluids, such as hydraulic and shock absorber fluids. Lard oils are being used as cutting, quenching and honing oils. They are also being used in all-natural drawing and stamping fluids. PFAU has several grades that are designed for cement mold release applications. The free fatty acids in the oil react with the cement to make a soap. This allows the lubricant to be both a chemical and physical mold release agent.
