NeverWet® coatings are superhydrophobic surfaces.
Water on our surfaces sits as an almost perfect sphere. Water beads "glide" over our surfaces like a skate gliding over ice, with almost no surface friction.
The contact angle of water on a surface is the angle of the leading edge of a water droplet on the surface as measured from the center of the droplet. A surface with a contact angle of 180 degrees would mean that water sits on it as a perfect sphere. Hydrophobic surfaces are measured between 90 degrees and 180 degrees. Below is a graph comparing the contact angles of common hydrophobic surfaces.
Here are the contact angles of water on various surfaces:
