Solvent-free Signo Flexiguard is made up of silicon dioxide molecules
whose surface energy is modified by anti-bonding molecules. On application
to the porous substrate, silicon dioxide molecules from the coating
and the substrate start to bond together releasing the anti-bonding
molecules. These molecules migrate to the surface creating an ultra-smooth,
protective outer layer, and changing the status of the porous substrate
from high to low energy. This low-energy status is fundamental to
the repellent qualities offered by treated surfaces.
| As the silicon dioxide molecules (blue/grey) in Signo Flexiguard
bond seamlessly with those lining the inner pores of the substrate,
the anti-bonding molecules (brown) form a highly protective, breathable
surface layer. By preventing a build-up of water, dirt or oil,
the growth of mould, fungi, moss and bacteria (green) is inhibited. |
