Just as metal rusts, glass is subjected to a corrosion process caused by reactions between the glass surface and gases in the atmosphere. Even a single droplet of moisture on protected glass can produce sufficient damage to be visible in good lighting:
The surface of glass is not smooth and consists of microscopic peaks and potholes. Both organic and inorganic contaminants fill these potholes and chemically react with the glass, firmly bonding to the surface. Because of this, cleaning glass becomes more difficult and visibility deteriorates.
To learn more about glass corrosion
If you would like to know more about the process of glass corrosion, why not take a look at the specialist article written by Ritec International’s MD Stephen Byers.
ClearShield: The Ideal SolutionClearShield is a polymeric resin and, when applied to ordinary glass, it cross-links to form a strong chemical bond. ClearShield is completely transparent, chemically inert, non-hazardous and UV stable. Unlike a coating, ClearShield becomes part of the glass so will not peel, flake or crack.
The result is ClearShield Low-M (Low-Maintenance) Glass ® that prevents contaminants from bonding to the surface and limits further damage caused by corrosion and chemical attack. Dirt can easily be removed using normal cleaning methods.
