Example 1:
Nano particles organize themselves and bond together with the sealed surface to a firm connection . This happens for example with glass and ceramics. After the sealing fluids and dirt expire a lot more simply of the surface.
Example 2:
If a facade is sealed, the nano particles fix themselves on the open pores. After that dirt and water can expire more simply, but the surface still remains open for diffusion. Fungus, weaving, algae and moss are disturbed in the growth and therefore can’t survive.
Examples 3:
Textiles can be sealed also. The nano particles form protection layer around each single fiber. Moisture and dirt can no longer penetrate into the fibers.
