Spray On Liquid Glass

Looks good and claims to do just about everything (include coat the kitchen sink)!

A real break thru. My only concern is the fact it is a nano particle product (unknown long-term safety issues) and it is also soon to be available for purchase by anyone as a liquid spray. As long as it binds together (rather than floating around as dust) then it should be as safe as claimed.

Well, if it kills you they can always coat the headstone so it lasts forever. But wait, they're saying the coating lasts "a year". Where does it go, when it's worn off then?

Ah, I knew they were blowing when they said they'd make cleaning products obsolete! There'll always be dust.

Anyway, a thicker spray of glass might work as well for some things. Would the particles be fused better then I wonder, as in a real piece of glass. Or would it always be not-quite-glass with very sharp inhospitable surfaces on a bacterial scale.

Itz probably some kind of uni-molecular polymer with glass added. That would explain the 'quantum' property (or merely an exchange of electrons?).

I'd be interested if it could be used on fibreglass hulls and the woodwork..

hmmm. I got quite a few hits at PubMed for "silica nanoparticles" that's as close as it gets to spray glass - apparently there are a huge number of biomedical applications for silica nanoparticles.

not a big lot of health studies, according to this. there could be a bioaccumulation risk at least for injected SiNPs. So I guess it depends how much ends up inhaled or injested from the everything it will be sprayed on. Give it.. forty years?

Yeah, it could be a real winner for wood. I'll be interested to see how it holds up under wear and tear.

Bet Maple Leaf Foods and the recurring listeria histeria would be a candidate

If it is resistant to many chemicals, how do you strip it to re-coat after it has worn? I'm thinking along the lines of coating Lexan racing windscreens to resist scratching to increase their useful lifetime.

I would like to be convinced that this stuff is not the new asbestos. Somebody explain to me why this material won't fracture into microscopic particles that have toxic properties such as silica dust has toward human lung tissue. Then I'll get enthusuastic about it.

Apparently, carbon nanotubes are a good candidate for "the new asbestos", according to this article reviewing what is known about nanotoxicology.

New invention? A similar compound has been used to coat semiconductor wafers for decades.

Silicafilm is very fine SiO2 suspended in an alcohol/water matrix.

100 nanometer thick should be 150 to 300 molecules thick not 15-30. Perhaps they meant angstroms instead of nanometers. I can't imagine that 300 molecules thick of glass would be very breathable.

Good point! Leads me to wonder who in fact this outfit is.
