Innovative Coatings for Easier Cleaning


Nano-Effect

After applying on smooth surfaces the nanoparticles organize themselves in a layer and combine with the surface.

On sucking materials like textiles or wood, the coating material infiltrates the pores and covers each fiber. Moitsture and dirt particles can‘t permeate into the fibers because of the hydrophobicity, and run of like pearls.

Appearance, breathability and grip of all treated materials remain the same.

On smooth surfaces they cross-link with the surface. The result is that e.g. on hydrophilic surfaces, liquids can run of like pearls and take away dirt particles.

Nano-components Textile fibers


On hydrophobic surfaces, water runs off like pearls.

A dimension for hydrophobicity on smooth surfaces is for example the contact angle. The angle build by a liquid drop on the surface to this surface is called contact angle.

A surface is called hydrophobic when the contact angle is above 90° compare to water.

Hydrophobicity

Measurement of a contact angle (Kontaktwinkel)

Waterdrops run down and take away dirt particles on inclined surfaces.

The contact surface for dirt particles is extremly reduced by the microstructure of the surface.

This surface is not hydrophobic and has no microstructure. It is more moistened by water, and dirt particles can adhere.

Photocatalytic self-cleaning coating for glass and plastic surfaces

Especially suitable for facades, weather side, because the photocatalysis need water in sufficient quantity Improvement of light efficiency The surface tension against condensation water is increased above the air/water-value, hence results a total flowing of the condensation water.

Photocatalysis-Process Titanium dioxids is a semiconductor, UV-light generates electon-hole-pairs, that diffuse to the surface Particularly the holes have a high oxidation effect, they turn water (H2O) into OH-radicals. These radicals generate hydrogen peroxide together with oxigen Organic substances can be decomposed
