NavGuard IV

MIL-PRF-81309H Type IV Qualified Advanced Corrosion Prevention Compound

Maximum long-term corrosion protection for military, aerospace, marine and industrial assets.

NavGuard® IV is the advanced-performance member of the NavGuard® family, developed for applications where maximum corrosion resistance and extended maintenance intervals are critical.

Developed by the U.S. Naval Air Systems Command (NAVAIR), NavGuard® IV was designed to provide significantly longer-lasting corrosion protection than conventional corrosion preventive compounds used in naval aviation. Its advanced ultra-thin film technology forms a durable, self-healing protective barrier that actively displaces moisture, protects multiple metal substrates and remains flexible under thermal cycling, vibration and mechanical movement.

Qualified to MIL-PRF-81309H Type IV, NavGuard® IV is intended for corrosion-prone areas where long-term preservation and maximum asset protection are required.

Why Choose?

Why Choose NavGuard®?
NavGuard® is a family of advanced Corrosion Prevention Compounds (CPCs) originally developed by the U.S. Naval Air Systems Command (NAVAIR) to provide significantly longer-lasting corrosion protection for military aircraft operating in the world's most demanding environments.
Qualified to MIL-PRF-81309H, NavGuard® is one of only a limited number of corrosion preventive compounds meeting this demanding military specification. Developed in accordance with MIL-PRF-81309H, its advanced ultra-thin film technology provides outstanding protection against moisture, salt spray and corrosive environments while maintaining full inspectability of treated components.
Compared with conventional military-grade CPCs, NavGuard® was engineered to extend corrosion protection intervals, helping reduce repeat applications, minimise maintenance downtime and lower total lifecycle costs for aircraft and critical assets.
According to Corrosion Technologies, qualification and comparative testing demonstrated corrosion resistance significantly exceeding the minimum requirements of MIL-PRF-81309H. Laboratory testing in accordance with ASTM B117 showed corrosion protection lasting approximately three times longer than the specification's 14-day neutral salt spray requirement on aluminium test panels. Comparative evaluations also demonstrated substantially improved corrosion protection on aluminium and steel when compared with conventional commercially available corrosion preventive compounds.
Its advanced low-viscosity formulation penetrates deep into seams, lap joints and enclosed cavities before forming a durable, ultra-thin protective film. Once applied, the coating remains flexible and is unaffected by thermal expansion, vibration and mechanical movement. It will not crack, sag, fatigue or peel throughout its service life.
NavGuard® provides outstanding multi-metal corrosion protection for steel, aluminium, magnesium and their alloys, while helping reduce both anodic and cathodic corrosion and slowing the diffusion of corrosive agents into protected surfaces.
The ultra-thin, low-build coating does not attract dust or dirt, adds virtually no measurable weight to aircraft structures and does not interfere with routine inspection or maintenance procedures. The formulation is free from waxes, silicones and heavy metals, features a low VOC content and is safe for use on electrical systems, electronics and avionics.
NavGuard® may be applied during manufacturing, shipment, long-term storage or routine in-service maintenance and can be recoated whenever additional protection is required.
Products within the NavGuard® family have been assigned National Stock Numbers (NSNs) and are available for procurement through the U.S. Defense Logistics Agency (DLA), reflecting their suitability for military, aerospace and government applications.
