Photocatalytic and superhydrophilic properties.
Surfaces treated with PhotoACTIVE become self-cleaning. Through the process of photochemical oxidation, organic matter (such as bacteria or fungi) is decomposed into water vapor and non-toxic minerals.
Non-porous surfaces, such as glass and bright finishing, become highly hydrophilic, meaning that they have a reduced water contact angle – preventing water from forming droplets. They become easier to clean, limiting the accumulation of grime and biofilm, without generating any visual distortions or cloudiness on clear glass.
Many self-cleaning solutions used by the glass industry rely on hydrophobic technology. An hydrophobic treatment increases the surface tension of glass to repel water. Water slides easily off the glass surface, reducing the amount of residual water droplets. Unfortunately, traces of limescale can remain after drying.
By contrast, surfaces coated with PhotoACTIVE become super hydrophilic: rather than eliminating water from the surface, water will spread forming a very thin layer. This, combined with an increased surface area exposed to air, helps speed up the evaporation process and eliminates the risk for limescale stains.
The photocatalytic properties of PhotoACTIVE lead to the degradation of the biofilm and organic matter on the now self-cleaning surfaces.
Understanding superhydrophilicity:
- Shapes water so as to eliminate residue
- Takes advantage of the natural properties of a mineral to eliminate dirt from the surface
- Eliminates the risk of droplets forming. The accelerated evaporation process prevents limescale deposits.
