Nano Tech: Spray On Liquid Glass

It makes your clothing invincible to the elements. SiO2 Ultra-Thin layering spray coats clothing with a thin protective layer that repels dirt, heat, UV radiation, and infections.

The image shows the SiO2 coating on a filament of a microfibre, illustrating the 100 nanometer thick protective layer.

"... 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."


"A year-long trial of the spray in a Lancashire hospital also produced "very promising" results for a range of applications including coatings for equipment, medical implants, catheters, sutures and bandages. The war graves association in the UK is investigating using the spray to treat stone monuments and grave stones, since trials have shown the coating protects against weathering and graffiti. Trials in Turkey are testing the product on monuments such as the Ataturk Mausoleum in Ankara."
