SELF-CLEANING, REPELS WATER, BREAKS DOWN FAT, KILLS BACTERIA
For one, the protective layer causes SP TITANIUM a reduction of the surface tension and thus preventing the droplets formation. This bounce off water droplets from the surface of the screen. This is referred to often as the hydrophobic effect or as the Lotus effect.
On the other hand, the nano particles which ionize SP titaniumProtective layer under the influence of sunlight. While they produce active oxygen, which in turn splits most fats and kills bacteria. This is also known as the Honda-Fujishima effect.
