Spray-on Glass

Whaaaaaaa?

From Telegraph UK

Liquid glass, a revolutionary invisible non-toxic spray that protects against everything from bacteria to UV radiation, could soon be used on a vast range of products.
The spray, which is harmless to the environment, can be used to protect against disease, guard vineyards against fungal threats and coat the nose cones of high-speed trains, it has been claimed.
The versatile spray, which forms an easy-clean coating one millionth of a millimetre thick – 500 times thinner than a human hair – can be applied to virtually any surface to protect it against water, dirt, bacteria, heat and UV radiation.
It is hoped that liquid glass, a compound of almost pure silicon dioxide, could soon replace a variety of cleaning products which are harmful to the environment, leaving our world coated in an invisible, wipe-clean sheen.
The spray forms a water-resistant layer, meaning it can be cleaned using only water. Trials by food-processing companies showed that sterile surfaces covered with a film of liquid glass were equally clean after a rinse with hot water as after their usual treatment with strong bleach.
The patent for the technology is owned by a German company, Nanopool, which is in discussions with UK companies and the NHS about the use of liquid glass for a wide range of purposes.
Several organisations are said to be testing the product, including a train company in Britain, which is using liquid glass on both the interior and exterior of the train, a luxury hotel chain, a designer clothing company and a German branch of a hamburger chain.
Key to the product's versatility is the fact it can be sold in a solution of either alcohol or water, depending on what surface needs to be coated. The layer formed by the liquid glass is said to be flexible and breathable.
Neil McClelland, Nanopool's UK project manager, told The Independent: "Very soon almost every product you purchase will be protected with a highly durable, easy-to-clean coating ... the concept of spray-on glass is mind-boggling."

From Nanopool:
The flexible and breathable glass coating is approximately 100 nanometres thick (500 times thinner than a human hair), and so it is completely undetectable. It is food safe, environmentally friendly (winner of the Green Apple Award) and it can be applied to almost any surface within seconds . When coated, all surfaces become easy to clean and anti- microbially protected (Winner of the NHS Smart Solutions Award ). Houses, cars, ovens, wedding dress or any other protected surface become stain resistant and can be easily cleaned with water ; no cleaning chemicals are required. Amazingly a 30 second DIY application to a sink unit will last for a year or years, depending on how often it is used. But it does not stop there - the coatings are now also recognised as being suitable for agricultural and in-vivo application. Vines coated with SiO2 don't suffer from mildew, and coated seeds grow more rapidly without the need for anti-fungal chemicals. This will result in farmers in enjoying massively increased yields . Trials for in-vivo applications are subject to a degree of secrecy, but Neil McClelland, the UK Project Manager for Nanopool GmbH, describes the results as "stunning". "Items such as stents can be coated, and this will create anti sticking features - catheters , and sutures which are a source of infection, will also cease to be problematic."
