The APC400 Icephobic Protection Series is a breakthrough in anti-icing protection layer solutions


The AeroPel APC400 Icephobic Series actively prevent ice nucleation, reducing ice adhesion strength by several orders of magnitude below any other available coatings.

Extensive Testing

AeroPel Icephobic was tested by the Air Force Research Laboratory and Army CRREL. The Air Force Research Laboratory called AeroPel Icephobic, ``the best icephobic coating ever tested.``

Record Setting

n testing at the U.S. Army Cold Regions Research and Engineering Lab (CRREL), Aluminum 6061 was treated with AeroPelTM and registered ice adhesion strengths of just 5.1kPa - the lowest result ever recorded at CRREL.

AeroPel APC400 Series

The AeroPelTM APC400 Ice Protection Series provides a superhydrophobic Nanocomposite Protective Layer (NPL) designed to repel water, limit ice nucleation, and minimize snow accumulation.  Ice protection NPL is stable under extreme UV and ozone exposure.

The superhydrophobic properties of the APC400 Series vastly reduces the contact angle between water and treated surfaces, and in tests conducted by the Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) was demonstrated to reduce ice adhesion strength to several orders of magnitude below any other commercially available coating.

The APC 400 Series NPL was developed specifically for aviation applications, ice protection NPL uses proprietary nanotechnology to create a super-hydrophobic surface on existing substrates that can repel water and drastically minimize ice buildup.  In addition, ice protection NPL provides excellent corrosion protection for the substrate preventing direct exposure to the environment. 

The Ice protection NPL was lab and field tested to evaluate performance in prevention of ice build-up and minimizing of galvanic corrosion, the APC400 Series has been lauded by the U.S. Air Force Research Laboratory as ‘the best icephobic coating (they had) ever tested.’

The aviation industry in particular is heavily impacted by complications from icing, which can lead to effects such as galvanic corrosion. Galvanic corrosion is caused when two dissimilar metals with a wide difference in electrochemical potential come into contact and trigger an electrochemical reaction, causing the readily oxidizing metal to corrode.

One of the main hazards in cold weather operations of aircraft is the formation of ice on the airframe, particularly the wings and flight control surfaces. Icing on the ground, and from flights in known icing conditions, may quickly cause adverse effects if precaution is not taken. Icing may also affect certain power plant components and may reduce optimized performance.

Potentially, ice protection NPL may eliminate the traditional aircraft de-icing process in cold weather operations.  With the surface having an ultra-low ice adhesion strength, a more environmental-friendly process such as high pressure air or water may be used to displace any ice and snow instead of harmful chemicals.

The APC400 Series has been tested with commercial aviation partners over eight months on aircraft operating in highly corrosive, inter-island environments. The components that were treated exhibited no signs of corrosion or color change over those eight months.

The APC400 Series is optimized to minimize icing and corrosion in aluminum components in the aircraft by imparting extreme levels of superhydrophobicity through a proprietary, nanomaterial-based composite coating, which provides unparalleled water and ice repulsion. Benefits include:

  • Excellent water and ice repellency under extreme weather conditions
  • Ultra-low ice adhesion strength on protected surface
  • Superior corrosion protection in highly corrosive environments
  • Stable and functional in extreme conditions from -60°F to 400°F (-51°C to 204°C)
  • Improves overall operational efficiency and provides long term savings
