If a droplet on a material forms a sphere where the contact angle is less than 90 degrees then the surface is defined as being hydrophilic, or water-loving (from the Ancient Greek words hydro for water, and philos for love). The term defined as superhydrophilic is used for surfaces with a water contact angle of less than 20 degrees, where droplets would spread out nearly flat.
The EASI-Plasma Nano Coating Technology creates the hydrophilic properties by adding an extremely thin silica coated layer, with a thickness between 5 and 50 nm (0.005-0.05 microns).
The EASI-Plasma Nano Coating adds a permanent superhydrophilic surface ability with a tuneable low contact angle (5° – 20°). Furthermore it also provides the benefit extremely good adhesion (72-105 dyn/cm).
