Self-Cleaning Glass?
Several international
glass manufactures have launched
‘Self-Cleaning’ Titanium Dioxide
coatings in selected countries across
Europe and America.
2 important
properties
It is hydrophilic.
That is - it attracts
water and causes it to ‘sheet’ on
the surface of the glass.
This prevents the
formation of separate droplets and
ensures that loose particles of dust
and dirt can be washed away easily
during normal rainy weather.
It is photocatylic
– UV radiation causes the coating to
oxidise dirt and organic deposits,
loosening them from the surface of
the glass.
ClearShield is
hydrophobic –
it prevents the
retention of water in the pores of
the glass surface and therefore the
bonding of contaminants, both
organic and inorganic.
It also protects glass against
corrosion, avoiding staining and
discolouration and keeping glass as
an easy to clean surface.
