How our classic biomimetic technology, Lotusan®, works

We introduced our Lotusan® facade paint as our first-ever biomimetic product back in 1999. It is now referred to worldwide as a perfect example of a principle from the natural world being applied to technology. With its clever architecture made up of filler material, its microtexture mimics the surface of a lotus leaf. And so it offers an effective solution when it comes to one of the most important jobs of facades: water management. Dew, rain, and fog don’t have a chance to stick to the surface and instead they simply run off. Algae and fungi are deprived of the nutrients they need to grow, leaving the facade looking pristine.

Conventional facade coatings:

Dirt particles form a deposit on the surface.

Conventional facade coatings:

The surface is less hydrophobic and is therefore more wettable with water. Dirt particles can adhere better.

Dual function of facade coatings with the Lotus-Effect® Technology:

Function 1: facade coatings with Lotus-Effect® Technology have a microtextured surface. This means the contact area for dirt particles and water is significantly reduced.

Dual function of facade coatings with the Lotus-Effect® Technology:

Function 2: the surface is also super hydrophobic. Raindrops run off and simply take the loosely attached dirt particles with them.
