These are dewatering fluid, anti rust lubricant containing oil soluble surface-active agent dissolved in a solvent with suitable corrosion- preventive and film forming materials. It contains selected additives which impart excellent ability to wet metal surfaces in preference to water. It can be applied at room temperature by dip or spray method. The film formed over metal surfaces can be easily removed by dipping the parts in suitable solvent.
This oil provides effective protection against rust on to the work-pieces during short-term storage in between operations. When the work-piece is dipped in the oil the water adhering to the metal surface gets dislodged by a thin film of this product. After the application, the solvent evaporates, leaving a soft grease like protective film on the metal surface.
