Spray-on liquid glass is about to revolutionize almost everything

The liquid glass spray (technically termed “SiO2 ultra-thin layering”) consists of almost pure silicon dioxide (silica, the normal compound in glass) extracted from quartz sand. Water or ethanol is added, depending on the type of surface to be coated. There are no additives, and the nano-scale glass coating bonds to the surface because of the quantum forces involved. According to the manufacturers, liquid glass has a long-lasting antibacterial effect because microbes landing on the surface cannot divide or replicate easily.

Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. Research on the product was carried out at the Saarbrücken Institute for New Materials. Nanopool is already in negotiations in the UK with a number of companies and with the National Health Service, with a view to its widespread adoption.

The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. On this nanoscale the glass is highly flexible and breathable. The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. UK project manager with Nanopool, Neil McClelland, said soon almost every product you purchase will be coated with liquid glass.
