Signo Glassguard is the strongest and most durable glass improvement
system available. Once applied, a protective layer less than 100-nm
thick (80,000 times thinner than a human hair) bonds with the substrate
to leave a smooth, anti-stain, nondiscolouring surface layer.
The coating is crystal clear, UV stable, chemically inert and
extremely durable, having both hydrophobic and oleophobic capabilities.
It will not peel or flake and is unaffected by extremes of temperatures
from –20°C to +350°C.
Signo Glassguard offers protection against:
- Discolouration of glass from contaminated air and road traffic
- Chemical attack including, oxide corrosion by acid rainwater,
damage by alkaline run-off from construction materials such
as cement, concrete and plaster, and from fat, grease and oil
- Corrosion by salt and other climatic coastal and marine conditions
- Etching by electrostatic particles from train, tram and metro
networks, and by rust particles.
