The applied sealant forms an invisible film on the surface that, when triggered by sunlight / UV rays in what is called a photocatalytic process, breaks down "muck" and dirt to the point that they are easily carried away by rain or water.

The product protects glass and synthetic surfaces from being tarnished and helps prevent the accumulation of dirt and other contaminants and is best suited to applications such as solar panels, and commercial and residential glass where accessibility to clean on a regular basis is an issue.

"The coating is 30 nanometers thick, which adds zero weight (a human hair is 80,000 nanometers thick)." (see Related Information link)

"Nanoparticles are man-made and primarily a mix of silica (not silicone), ceramic, silver and/or titanium. The exact formula depends on the application and the benefits to be achieved." (see 'What Is Nanotechnology?' page of company website under 'About')
