Fogging is a problem

Let things always be crystal clear. Don’t be blinded by moisture ever again. Discover the magic of anti-fog coating technology.


Why does fogging occur on surfaces?

Fogging occurs as a result of a phase change in matter. A common example can be observed in warmer, more humid countries when the water vapour present in the air comes into physical contact with the cooler lenses of eyeglasses. As a result of the drastic temperature differences between the two, the vapour turns into liquid on the surface of the lens.

Anti-fog Coating

The Anti-Fog treatment X-FogTM, developed by Advanced Nanotechnologies S.L. (AN), is a patented technology that achieves excellent results in a wide variety of applications. To prevent the surface condensation that occurs due to large differences in exterior and interior temperature, AN has designed a permanent nano-coating for plastic and glass substrates with anti-fog materials that leave surfaces “fog-free”. This technology is possible due to a two-step process of surface treatment and maintenance.

What can our anti-fog coating be useful for?

  • Eyeglasses
  • Safety glasses
  • Goggles
  • Diving masks
  • Motorcycle helments
  • Mirrors
  • Automobile parts
  • Camera optics
  • And more!

Surface treatment
In order to deposit the anti-fog material, it is necessary to use ultra-high vacuum machines (UHV), which are based on Physical Vapor Deposition (PVD). This allows us to achieve a nano-thin layer of material.

In order to always maintain the anti-fog effect on the now treated substrate, it must be cleaned with a special wipe that has been developed by AN. Simply breath on the substrate to fog it up, and then run the AN wipe over the substrate. Do this before every use to ensure maximum performance.
