NAVGUARD

Navguard 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 on the CPC film. The compounds used for this CPC mildew inhibiting formulation are readily available, environmentally benign and are cost effective. Standard industrial techniques and chemical processing methods can be utilized in fabricating and packaging this CPC product in large quantities. The effectiveness of the mildew inhibitor additives into Navguard and selected products from MIL-C-81309 and MIL-C-85054 specifications was performed at the Naval Research Laboratory at Stennis Space Center and showed good results on all tested products. In addition to preventing mold growth, the 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 aircrafts. Navguard was developed in accordance with MIL-PRF-81309 (Corrosion Preventive Compounds, 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. Summary of Benefits Cost effective formulation from commercially available chemicals; Foggable by using aerosolizing nozzle; Low VOC content and environmentally friendly composition; Compatible with metal and non-metal components; A water displacing agent; Extremely effective corrosion inhibitor for aluminum, magnesium and steel alloy surfaces; Previously treated surfaces require no removal process; Durable coating that provides long-term protection on multiple metal surfaces.
