The nano-particles in the coating strongly attract the water droplets and force them to form much smaller contact angles with the surface,

The coating basically causes water that hits the surfaces to develop a sustained sheeting effect, and that prevents fogging.

They remain stable over long periods, do not require light to be activated and can be applied to virtually any surface.

As a result, the droplets flatten and merge into a uniform transparent sheet rather than forming countless individual light-scattering spheres.

Gutta cavat lapidem, non vi, sed saepe cadendo. - A drop of water hollows a stone, not by force, but by continuously dripping

The force is really strong. Imagine 500 gallons of water coming out at once. The pressure is unimaginable.
