wettability (wet´əbil´ətē),

n the angle at which a droplet of liquid interfaces with a horizontal surface; the shape of the droplet varies depending on the type of liquid and surface, thereby influencing the contact angle and thus the wettability. The greater the angle past 90°, the greater the wettability.
