The lotus effect refers to the very high water repellency (superhydrophobicity) exhibited by the leaves of the lotus flower (Nelumbo).[1] Dirt particles are picked up by water droplets due to a complex micro- and nanoscopic architecture of the surface, which minimizes adhesion.
This effect can easily be demonstrated in many other plants, for example tropaeolum, cane and columbine, and on the wings of certain insects.
The phenomenon was first studied by Dettre and Johnson in 1964 using rough hydrophobic surfaces. Their work developed a theoretical model based on experiments with glass beads coated with paraffin or PTFE telomer. The self-cleaning property of superhydrophobic micro-nanostructured surfaces was discovered in the 1970s[2] and has been applied since the 1990s[3] in biomimetic technical products.[4][5][6][7][8][9] Perfluoroalkyl superhydrophobic materials were developed in the mid 1990s for use with chemical and biological fluids.

Easy-to-clean coating for glass - Invisible non-stick coating
dirt-repelling coating formula for applying to ceramic and glass substrata for example glass facades, canopies, winter gardens, solar panels, mirrors, automobile glass, shower partitions and glass panels
This coating was planned so that surfaces receive less contact from dirt particles. Through the hydrophobe and oleophobe effect, dirt particles such as greasy and oily substances, lime, and environmentally harmful materials have less of a hold on the substrata or can be removed easily from the coating, i.e. without abrasive means
- powerful hydrophobic and oleophobic properties
- anti-lime effect
- the appearance of the substratum
- is not affected
- tremendous friction resistance
- easy to apply
- short drying period. Can be stored directly after application
- self-drying in 24 hours at room temperature
- high-pressure/steam cleaner proof
- high efficiency through economical use (5-10 ml per m²)
- tolerant of high temperatures (up to 450° C peak temperature)
