Additionally, when Levasil Colloidal Silica is used in glass cleaning products, water is less likely to form droplets or fog on the surface, so called anti-fogging.
Dirt is attracted to surfaces that are hydrophobic, in other words, afraid of water. When surfaces are more hydrophilic, or water loving, dirt is repelled. This is called anti-soiling.
Silica particles in colloidal silica dispersions have many surface hydroxyl-silanol groups, which are very hydrophilic. Thanks to the enrichment of colloidal silica particles in the coating surface you get a less tacky and more hydrophilic surface. This means that water forms a film on the surface, allowing dirt to run off with the water.
