AeroPel NPL is a surface designed to repel moisture and fluid for corrosion prevention, reduce surface friction for enhanced fluid flow, limit ice nucleation for ice protection, and minimize ice/snow accumulation for ease of de-icing.
Airframe Protection
Corrosion: One of the biggest challenges in airframe maintenance
Airframe corrosion, and the efforts to maintain a robust corrosion prevention and control program, can be a significant and hidden cost for any operator. While advancements have been made, multiple protective measures can still fail sequentially over time allowing corrosion to occur. AeroPel NPL offers the aviation industry a 21st century solution to turn corrosion into history!
AeroPel APW100 Series Product Sheet
CIC Failure
An example of Corrosion Inhibiting Compound (CIC) failing and flaking off from the substrate because of extreme operating conditions.
Airframe Damage
An example of fuselage skin & frame corrosion damage. Moisture sequentially penetrated CIC, primer, and chemical conversion.
Fuselage Skin Damage
An example of fuselage skin corrosion damage caused by exhaust vent moisture that sequentially penetrated the organic-based topcoat, primer, and chemical conversion.
Ice Protection
Unprecedented Superhydrophobic Surface Limiting Ice Nucleation
AeroPel NPL Ice Protection Series
Key Performance Properties for Surface with AeroPel NPL Applied
Water droplet contact angle >160° (compared to approximately 80° on bare substrate)
Receding angle of water droplet is >130° (compared to approximately 60° on bare substrate)
Roll off angle is <10°
Ice adhesion strength is 0.71 psi (5.1 kPa) compared to bare substrate which is > 174 psi (1200 kPa)
Operating temperature is -58 to 480° F (-50 to 250° C)
Extensive Testing: Developed specifically for the aviation industry, AeroPel NPL was tested by the Air Force Research Laboratory and US Army Corps of Engineers Cold Region Research and Engineering Laboratory (CRREL). The US Army CRREL called AeroPel NPL “the best icephobic coating (they had) ever tested”.
