Rust preventive oil is composed of base oil and rust inhibitors. This type of oil focuses on rust prevention and can be customized for different rust protection periods depending on the specific surface requirements of the workpiece. For instance, if the workpiece has residual moisture, as is the case after emulsification processing, dehydrating rust preventive oil can be used, such as OFILL's F209 displacement rust preventive oil, which offers excellent dehydrating and rust protection properties. On the other hand, if a clean workpiece surface is required, volatile rust preventive oil can be used, such as OFILL's F206 volatile rust preventive oil, which leaves a thin rust protection film after evaporation. For workpieces that need to be preserved, OFILL's F205 lubricating rust preventive oil can be a suitable choice.

Lubricating rust preventive oil can achieve a maximum rust protection period of 3 years.

The rust protection period of hard film rust preventive oil is around 2 years.

Volatile rust preventive oil typically offers rust protection for about 6 months to 1 year. For instance, when a metal surface is required to be relatively oil-free and have a longer rust protection period, you can choose volatile rust preventive oil. It has good volatility, easy cleaning after application, and provides rust protection for approximately 1-1.5 years.

Dehydrating rust preventive oil typically provides rust protection for about 6 months to 1 year. For workpieces processed with water-based machining fluids, such as cutting parts, stretching parts, phosphated parts, blackened parts, and electroplating rinse parts, dehydrating rust preventive oil can be chosen. It offers effective dehydrating, quick dehydrating, and rust protection for approximately 6 months to 2 years. If a workpiece requires an oily film on the surface that is in an oily state and relatively thick, it is also recommended to use oil-based rust preventive oil, which has strong resistance to salt spray and provides long-lasting rust protection.
