Icephobic

AeroPel APC200 and APC400 series are icephobic coatings that actively prevent ice nucleation, reducing ice adhesion strength by several orders of magnitude below any other available coatings.

Anti-Corrosion

AeroPel APW100, 200, 300, and 400 Series coatings deliver exceptional omniphobic protection against galvanic and atmospheric corrosion for airframe surfaces, environmental control systems, fuel tanks, and more.

Extensive Testing

Developed specifically for the Aerospace industry, AeroPel was tested by the Air Force Research Laboratory and Army CRREL. The Air Force Research Laboratory called AeroPel Icephobic, ``the best icephobic coating (they had) ever tested.``

Extreme Stability

AeroPel is stable and functional in environments up to 400 degrees Fahrenheit and reduces surface roughness to just 60-120 μinch after application on complex geometries/components.

How AeroPel Works

AeroPel is a family of next-gen aerospace coatings that impart omniphobic (water- and oil-repelling) corrosion protection and high levels of superhydrophobicity and icephobicity.

Corrosion: One of the biggest challenges in aviation

Preventing corrosion consistently to keep aircraft flying safely is one of aviation's oldest and most complex challenges. While advancements have been made, multiple protective measures can still fail sequentially over time, allowing moisture to reach the metal and cause dangerous corrosion damage.

Key Performance Properties

Contact angle of water with AeroPel is >160° in tests on glass, aluminum and copper alloys (compared with approx. 80° on untreated substrates)

Receding angle of water with AeroPel is >130° in tests on glass, aluminum and copper alloys (compared with approx. 60° on untreated substrates)

Roll off angle with AeroPel is <10° in tests on glass, aluminum and copper alloys

Ice adhesion strength with AeroPel is <10kPa, compared to uncoated aluminum ice adhesion which is >1200kPa.

AeroPel functions at a thickness of just 1.5mil post-curing and in a wide temperature range: -50 to 250 degrees Celsius.
