One of the biggest challenges in aviation is finding a way to consistently prevent corrosion and protect metallic airframe structures and components to keep aircraft flying safely.  In general, the goal is to minimize corrosion damage to a “Level 1” classification from one maintenance cycle to the next.  This is traditionally done by layering protective measures, sometimes including physical barriers, to prevent moisture from penetrating to the metal surface and initiating the corrosion process.  However, despite the industry’s best efforts, corrosion damage exceeding Level 1 is still an uncomfortably common occurrence.  Multiple protective measures can still fail sequentially over time, allowing moisture to reach the metal and cause corrosion damage.

AeroPel is a Nanocomposite Protective Layer (NPL) formulated to provide superior protection for airframe structures and components.  AeroPel NPL is the next generation in corrosion prevention, with other benefits and applications yet to be imagined.

How can AeroPel better protect against corrosion?

Based on breakthrough nanotechnology, AeroPel NPL repels moisture from the protected substrate by creating a low surface energy for the substrate, forcing moisture to bead up instead of “wetting” the protected area.  AeroPel NPL prevents moisture from remaining in full contact with the protected substrate, so the moisture is thus unable to break down protective measures over time, nor cause corrosion in the metal underneath.  With a superior bond strength to the substrate, AeroPel NPL provides a sturdy protective layer for both bare metal and surfaces already protected with other measures. AeroPel NPL is inherently durable and outperforms traditional organic-based corrosion inhibiting compounds.

The APW100 Airframe Protection Series is water-based and was developed to provide superior protection for metallic airframe structures and components against corrosion damage.

The resulting omniphobic surface repels all water- and oil-based fluids, one of the key factors to maintaining a corrosion-free environment. In addition, the APW100 Series is resistant to chemicals and abrasion to provide a durable protection for the substrate.

Low Surface Energy Concept - The water droplet on the left is placed on a bare aluminum surface compared to the water droplet on the right is placed on a surface protected by the NPL. Note the NPL is forcing the droplet to bead up instead of wetting the surface.

The APW100 Airframe Protection Series is an environmentally-friendly, water-based Nanocomposite Protective Layer, a first in the aviation industry for corrosion prevention measures. The APW100 Series is extremely durable and can also serve to protect against erosion, especially when used externally on an aircraft. Due to its strength, only a thin layer is required to provide corrosion/erosion protection, so the APW100 Series has a lower dry weight compared to traditional corrosion inhibiting compounds, saving weight to reduce fuel consumption and, ultimately, carbon emissions over the operational life of the aircraft.

Key Benefits

  • Strong adhesion – Minimize bond-line failure that would allow moisture to penetrate to the substrate and initiate the corrosion process
  • Low viscosity to penetrate and seal structural joints for better corrosion protection
  • Thin film resulting in reduced dry weight
  • Fast curing time – Less idle time within the workflow
  • Functional under extreme temperatures from -60°F to 400°F (-51°C to 204°C)
  • Non-VOC and non-biocidal – Minimal personal protective equipment required for personnel
  • Non-hazardous – No restrictions for transportation and storage
  • Solvent removable
  • Baseline NPL is transparent; tinting is optional for visual identification purposes
Example of failing traditional Corrosion Inhibiting Compound (CIC)
Fuselage skin & frame corrosion damage: Moisture penetrated CIC, primer, and chemical conversion.
Fuselage skin corrosion damage: exhaust vent moisture penetrated organic-based topcoat, primer, and chemical conversion.
Fuselage cargo door cutout structure: moisture penetrated CIC, primer, and chemical conversion.

NPL technology is the next generation of corrosion protection developed to replace current organic-based corrosion inhibiting compounds. AeroPel NPL protects metallic airframe structures and components against corrosion damage and may also be used to protect areas against erosion damage. AeroPel NPL is a two-part mixture with a pot life of 72 hours.

Due to its low viscosity, AeroPel NPL can be easily applied by spray application with an effective thickness of less than 1 mil. At room temperature, AeroPel NPL cures in under one hour, reducing workflow interruption. It also contains no VOCs, which allows for application in confined spaces without disrupting normal workflows or productivity.

Proven Technology

AeroPel NPL is based on a nanotechnology application with proven success in the energy and marine industries. The fundamental science behind Aeropel NPL has helped these two industries effectively prevent corrosion and erosion damage to a vast network of infrastructure and investment worldwide. Dealing with corrosion and erosion damage is a sustained and hidden maintenance cost shared by the entire industrial sector. AeroPel NPL is designed to apply the success of the prior iterations of this nanotechnology solution to the specific needs of the aviation industry, offering protection against corrosion as well as other potential advantages.
