SurfTec’s coating possesses nano-scale and micro-scale hierarchical structures that produce ultra-hydrophobic properties. Because water is repelled and does not fully wet the surface, any ice crystals formed on the surface have a smaller contact area at the interface with the coating and thus a lower adhesion to the surface.
Our coating decreases ice adhesion. While many icephobic coatings are not durable, SurfTec’s coating yields a robust protective layer that can withstand UV and weathering degradation and is designed to last for the life of the component on which it is deposited.
A centrifuge ice adhesion (CAT) test, performed at AMIL International Laboratory, revealed that our coating exhibits an adhesion reduction factor (ARF) of 3.3.
