NEI Corp., Somerset, N.J., reports that it has enhanced the performance of its anti-ice coating, Nanomyte SuperAi, a nanocomposite coating that imparts anti-ice properties to the underlying substrate. Rigorous testing has confirmed its efficacy under a variety of icing conditions. As a consequence of the engineered properties of the anti-ice coating’s formulation, it reduces ice buildup on surfaces, and provides a hard, dense, smooth finish.
Treated surfaces exhibit reduced ice adhesion, thereby reducing ice buildup. Precisely calibrated Ice Adhesion measurements showed that SuperAi has an Ice Adhesion Reduction Factor of greater than 5 (relative to a polished metal surface), indicating that Nanomyte SuperAi reduces the adhesion of ice by more than 80%, compared to smooth bare metal and painted surfaces. The performance remains unaltered after repeated icing-deicing cycles, as well as after mechanical abrasion. Further, icing wind tunnel experiments show that SuperAi allows ice to be removed with minimal force, confirming its usefulness under real-world conditions.
The coating can be applied to a variety of substrates, including plastic, metal, glass, and ceramic. In some instances, a suitable primer may be required for long term durability.
SuperAi is a single component coating that is easily applied by spray or brush. The dry film thickness can be adjusted to be in the range of 5 to 25 microns, and only one coat is required to cover the substrate. Current applications include structures where ice removal is a challenge: e.g., wind turbine blades, power transmission lines and cables, cellular phone towers, windshields and other glass surfaces in automobiles, aircraft wings, and unmanned aerial vehicles. SuperAi also provides corrosion protection, which is an added benefit. SuperAi enhances productivity for the user and provides rapid payback, as well as a good return on investment.
