Preservation of Naval Aircraft Engine

Previously the Indian Navy had a very cumbersome, time consuming, labour intensive and expensive method of preserving their aircraft engines for a period of two years: 

• Moisture Barrier Bag - 1 no. • Paraffin Paper - 30 meters  • Silica Gel - 10 kgs • Rust Preventive Oil - 15 litres • Gasoline - 4 litres  • Poly Sheet - 20 meters 


Except for the Moisture Barrier Bag, these products were replaced every three months and the Silica Gel regenerated by heating. These products are toxic and cause lead poisoning. Additionally, it took one and a half days each quarter to renew this protection sys- tem. In spite of all this, the engines were still corroding during stor- age, and the customer decided to try Cortec’s solution. ​​​

Corrosion Inhibitors from Presserv UK fo

Corrosion Inhibitors were selected because they are clean and convenient to use.

Products only need to be applied once every two years. It takes just two hours to apply and 15 minutes to dismantle and remove. This is saving the customer valuable time, and by switching to this method, the customer saved 60-70% on current costs. Considering the fact that the Aviation Wing of the Navy, as well as the Indian Air Force itself, has a large number of engines to preserve, this was a huge savings for the Indian Defense Organization. Most of the Cortec® products are commercially equivalent to MIL Specs and offer far superior, reliable, and efficient inhibiting action, which has been proven worldwide. 


  • Cleaned all accessible surfaces of the engine with VpCI®-416 (1:6 solution).

  • Wiped these surfaces with Cortec® VpCI®-377 (1:9 solution)

  • Inserted VpCI®-132 Foam Pads (7 per engine), cutting to suitable size and placing them into various cavities, voids, intake and outlet chambers, and also on external surfaces of the engine.

  • Wrapped the entire engine with VpCI®-146 Paper and sealed.

  • Wrapped the equipment further with VpCI®-126 Film and sealed once again.

VpCI®-126 at 150 micron has Rolls Royce approval for military aircraft spares.

Unsealed tank bottom chime area

Concern over leaking in the chime area of storage tanks. Without sealing the chime area the ingress of air combines with water and accelerates corrosion, leading to leakage and the possible loss of the tank bottom.
