Our coating decreases ice adhesion by a factor of 3.3. 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 the coating exhibits an adhesion reduction factor (ARF) of 3.3.

 

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.

SurfTec’s coating exhibits an ARF of 3.3.

This reduction in ice adhesion, coupled with the ability of the coating to maintain functionality under UV and harsh weather conditions, makes the coating ideal for many applications.
