Product Description:

Exports of automotive components is a very critical task which requires specialised Rust Preventive Packaging schemes in synergism with highly effective rust preventive oils. RUSTX-EX Export Grade oils have higher, faster and longer duration of effective chemicals that protect the metallic components from saline atmospheres during sea transportation as well as long term storage. RUSTX 135 series rust preventive oils contain VCI chemicals, which work in contact phase as well as in the vapour phase and protect components by its dual action. RUSTX – 400 A is a viscous grade of rust preventive oil having excellent thixotropic properties and holds well on surfaces that may be super finished or vertically placed. The product has a high flash point and can be used for protection of Cold Rolled Steel, Engine Components, as well as large equipment where indoor open storages are required. The VCI action of the oil makes it suitable for spraying within hollow equipment such as boilers, heat exchangers, reactors, storage tanks, pipes etc. The VCI fraction evaporates and reaches hard to reach surfaces where the direct oil spray cannot reach and protects the equipment from corrosion.

Application Method:

Dipping by far is the best method for establishing an even layer on the component. Other methods may be used such as mist spraying, electrostatic spraying, brushing, automatic conveyor spray or dip process pray. It is important that the complete surface of the component is coated with the rust preventive oil.

Suitable for:

Machined Steel Components, Castings, Forgings, CR sheets, Bearings, Gears, Transmission Components, Axles, Process Equipment, Flanges, Valves etc.
