GBhydrophilic - Anti-fog coating

Water droplets and water vapour condensation on smooth surfaces can lead to optical interference and impede the transparency or reflection. Evaporation causes annoying spotting that may also affect the optics and can entail increased cleaning work.

Our clear, transparent hydrophilic functional layer achieves an improved wetting behaviour of the surface so that fine precipitating water droplets spread to form a cohesive thin film. This creates an anti-fog effect and prevents optical interference. The thin film of water also facilitates evaporation and makes for a cooling effect (greater energy-saving potential).
