Corrosion and Mildew Inhibitor

NavGuard I was developed to fulfill the need of the Navy for a longer lasting corrosion prevention film on Navy aircraft metal surfaces, while at the same time inhibiting the growth of mildew inside airframes.

The effectiveness of the mildew inhibitor additives in Navguard I was evaluated at the Naval Research Laboratory at Stennis Space Center and showed good results. In addition to preventing mold growth, the corrosion preventive compounds(CPC) film was found to last longer than currently used CPC systems, which would translate to fewer CPC treatments on aircraft, reducing down time and maintenance costs, and extending the life cycle of aircraft.

Navguard I was developed in accordance with MIL-PRF-81309 (CPC, Water Displacing, Ultra-Thin Film) and exceeds those specification requirements. For example:

  • Navguard lasted three times longer than the 14-day neutral salt fog (ASTM B 117) requirements for aluminum panels.
  • In side-by-side tests with other CPC products, Navguard products outperformed commercially available competitors by a factor of three on aluminum and steel.

This formulation is expected to perform equally well on other corrosion-sensitive surfaces. It has been tested successfully on aluminum, magnesium, and ferrous alloy surfaces.

NavGuard I provides high-performance, long-lasting, corrosion protection, without requiring repeated applications. This technology is also available without the mildew inhibitor additive (NavGuard II).
