(PhysOrg.com) -- Spray-on liquid glass is transparent, non-toxic, and can protect virtually any surface against almost any damage from hazards such as water, UV radiation, dirt, heat, and bacterial infections. The coating is also flexible and breathable, which makes it suitable for use on an enormous array of products.
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.
Food processing companies in Germany have already carried out trials of the spray, and found sterile surfaces that usually needed to be cleaned with strong bleach to keep them sterile needed only a hot water rinse if they were coated with liquid glass. The levels of sterility were higher for the glass-coated surfaces, and the surfaces remained sterile for months.
Other organizations, such as a train company and a hotel chain in the UK, and a hamburger chain in Germany, are also testing liquid glass for a wide range of uses. 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.
The liquid glass coating is breathable, which means it can be used on plants and seeds. Trials in vineyards have found spraying vines increases their resistance to fungal diseases, while other tests have shown sprayed seeds germinate and grow faster than untreated seeds, and coated wood is not attacked by termites. Other vineyard applications include coating corks with liquid glass to prevent corking and contamination of wine. The spray cannot be seen by the naked eye, which means it could also be used to treat clothing and other materials to make them stain-resistant. McClelland said you can pour a bottle of wine over an expensive silk shirt and it will come right off.
In the home, spray-on glass would eliminate the need for scrubbing and make most cleaning products obsolete. Since it is available in both water-based and alcohol-based solutions, it can be used in the oven, in bathrooms, tiles, sinks, and almost every other surface in the home, and one spray is said to last a year.
Liquid glass spray is perhaps the most important nanotechnology product to emerge to date. It will be available in DIY stores in Britain soon, with prices starting at around £5 ($8 US). Other outlets, such as many supermarkets, may be unwilling to stock the products because they make enormous profits from cleaning products that need to be replaced regularly, and liquid glass would make virtually all of them obsolete.
If we spray it on the Constitution will it protect it from Obama, Harry Reid and Nancy Pelosi?
Glass itself is a liquid, so why call it liquid glass ? Just say spray on glass.
Now that’s one excellent post and new development, LibWhacker. Thanks much. I’ll pass it on.
Were gonna end up sterilizing the whole planet and killing it.
That’s a myth:
By the way, the comments section below the article are interesting as well.
This sounds promising.
Gotta be a gazillion applications that would benefit from a surface coating like this.
no need for condoms anymore....just spray on some glass and you are squeeky clean!
Could I put it on golf balls to keep them like new?
Sounds like VIP
Can’t find anything harmful about it? Oh, give them time!
I wonder if it works on hair? Water off a ducks back. ;)
Maybe, but I prefer the liquid version — because it raises eyebrows.
It’s a FLOOR WAX!
No, it’s a DESSERT TOPPING!
I’ve never considered glass a liquid. Unless it is introduced to high heat.
Not spraying that on my weiner.
I wouldn’t want it on any part of my skin.
I agree. I doubt we can imagine all the possibilities
I thought silica was declared an environmental hazard. Hmmmm
I wonder if this liquid glass will fill in gouges in windshiels caused by sand and gravel.
useful product if we can get it before the “festivities” begin.
You clean it with di-hydrogen monoxide.
This sounds like the stuff they put on my wife’s new Honda.
OK. It’s spray-on, and it’s invisible. And it’s $8.00 a bottle.
Guarantee: You’ll never know (if) it’s there.
Apparently this is not the accepted scientific view now. The idea that very old windows have flowed slightly has been debunked.
"The notion that glass flows to an appreciable extent over extended periods of time is not supported by empirical research or theoretical analysis" - Wikipedia
GRRRREAT news and very interesting! Thanks for posting.
I had a Materials Scientist at LANL tell me that glass is technically a liquid, even at room temperature. But maybe it was the booze talking....
Ever see windows in an old building? Notice how the glass appears wavy, distorted? That’s because glass, a liquid, has been running and settling over the years in the window frame.
Look pal, I won't be intimidated by you or your freakish talking beverages, so there!
My sailboats brightwork is due for varnish come spring. I sure would like to try something like this product instead. When’s it ready for market?
I’m wondering if ingestion studies have been done with animals yet, or studies of eye irritant potential.
Be careful what you wish for.
The fine, micro-filaments of asbestos were thought to be harmless until, after 20 years of inspiration, the victims developed mesothelioma. What human consumption trials have been performed long term? Maybe the manufacturers can contract with McDonald's or KFC for a twenty year test..
are you sure it just not the process that they used to make the glass? I have never seen such a example in glass ware that is over 100-150 years old.
This wavy glass was made before truly flat, float or rolled sheet glass became common. It was made from spun disks.
I want some!
Thanks for the ping!
Same website, right side of page. They have it for sale.
“Glass itself is a liquid”
True, but most people won’t believe it.
Take a 60 year old piece of plate glass and measure it top and bottom and you will find that it has settled over the years with the bottom being thicker.
Something ELSE for the muslims to hate us for.
There was a show on “paint on” TV screens. I forget how, but electro-sensitive bits were added to a VERY thin film of plastic. The plastic was flexible and still showed the picture. They then spoke of imbedding it into paints and covering entire buildings, walls, etc. with it. So - add it to this spray on glass. (Or cover the building with the electro-paint and THEN cover with the glass).
Interesting questions BUMP!
