Rust-X | Rust Preventive Oil



Export Grade Rust preventives provide corrosion prevention against the most corrosive sea environment during exports. The VCI oils work in vapour phase as well as contact phase and protect the component for a longer duration providing longer packaged and storage life to the components. These are available in variety of grades with varying film thickness for various end use applications that match customer requirements of degreasing & dewatering properties, film thickness, colour, protection period, washability, smell etc.



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. RUSTX 135 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 - 135 A - Ex 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.


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.


  • Dry to touch
  • Good coverage due to low viscosity-high floatability & high penetration properties
  • Less consumption due to thin film
  • Quick Drying - Dries within 5-6 minutes
  • Doesn’t contaminate cutting fluids
  • Excellent protection against acidic and saline environments
  • Excellent Dewatering & Degreasing Properties
  • Finger Print Remover
  • Doesn’t produce fumes during welding or heat treatment
  • Non Sticky washable film
