A new hydroxy- (OH) functional silicone modified acrylate additive can enhance the surface-cleaning properties (cleanability) of coatings. Crosslinkable by way of OH-groups, BYK-Silclean[R] 3700 provides long-lasting significant improvements in cleanability so that adhering dust and dirt particles as well as graffiti can be removed much easier compared to "normal" surfaces.
The Lotus-Effect itself is based on surface roughness caused by microstructures (see Figure 3) in combination with a highly hydrophobic surface. The combination of both properties reduces the contact area between solid particulates or droplets of liquid on the leaf's surface drastically; liquids such as water, exhibit very high contact angles (see Figure 4).
