 VCI 400 A Description


pdf pdf

RUSTX 400 A Ex Dry series 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 Ex Dry rust preventive oil is used where dry to touch feel on the component is required without the need to wash the component before fitting. The thin layered rust preventive also reduces the amount of dust accumulation on the part as well as is an excellent rust preventive for OE supplies where assembly line use of the components is required.

Exports of automotive components are a very critical task which requires specialized 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.

Application Method

  • Dipping by far is the best method for establishing an even layer on the component. 
  • Other methods may be used such as spraying, Brushing, Automatic Conveyor & Spray Jet provided the complete surface of the component is coated with the rust preventive oil.
  •  135 A – Ex should be used with VCI packaging for best long term corrosion prevention results.
  • Use of gloves while handling the components as well as immediate packaging is important. In case the components carry cutting oils or water from previous processes, dewatering with CL005 is recommended.

Suitable For

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