Non PVDF lacquered surface & MEHATOPⓇ N lacquered surface
We adopted the principle of METHATOPⓇ N lacquering from natural role models. Many plants use their evolutionary, unique surface characteristics to protect their structure from environmental forces like fungi or algae growth.
The surface of METHATOPⓇ N treated membrane is designed in a similar way. A special nanostructure minimizes surface energy. The unique outcome of low surface energy is a significant reduction in the adhesive power of the surface when it comes to other molecules with higher surface energy such as water, dirt or dust.
The low adhesive power towards disperse and polar liquid molecules is the best demonstration of this effect. Materials with low surface energy do not attract a drop of liquid as strongly as material with high surface energy.
Therefore the droplet form is more stable. This effect is called hydrophobia, and it is measured using the droplet angle test.
A higher droplet angle indicates stronger hydrophobic capacity which results in better self-cleaning capacity of the surface.
