nucleation, reducing ice adhesion strength by several orders of magnitude below any other available coatings
AeroPel imparts extreme levels of superhydrophobicity and icephobicity to various substrates through a proprietary, nanocomposite formulation. The superior water-repelling properties actively prevent ice nucleation, eliminating ice build-up and protecting the treated substrate from atmospheric and galvanic corrosion in harsh environments such as humid and marine regions.
AeroPel was initially developed and tested for military aerospace icing applications. Tests conducted by the Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) showed AeroPel to reduce ice adhesion strength several orders of magnitude below any other commercially available coating. The impressive durability exhibited in these tests makes AeroPel suitable for other anti-icing/corrosion applications such as for wind turbines, bridges & railways, power transmission and other cables, communication towers, and many more applications.
The surface treatment is stable and functional in environment from -60 to over 400 degrees Fahrenheit and on complex geometries and components. Surfaces with AeroPel had contact angles with water of >160° in tests on glass, aluminum and copper alloys (compared with approx. 80° on untreated substrates). The receding angle of water with AeroPel is >130° in tests on glass, aluminum and copper alloys (compared with approx. 60° on untreated substrates).
AeroPel solves the need for an efficient, icephobic coating to combat ice and snow accumulation that can halt or negatively impact operations across a wide range of industries that must deal with ice-related operational impacts which result in millions of dollars being spent on repairs, delays, damages, and compensations each year.
- Cures in 24-48 hours (20 degrees Celsius) or 4 hours (75 degrees Celsius)
- Functional at thicknesses of 1.5mil (37.5μm) post-curing
- <5% change of thermal diffusivity for underlying substrate
- Ice adhesion strength with AeroPel is <10kPa, compared to uncoated aluminum ice adhesion which is >1200kPa
- Roll off angle is <10° in tests on glass, aluminum and copper alloys
