Does anybody know about this stuff?

Neverwet - hydropobic coating

http://www.youtube.com/watch?v=DZrjXSsfxMQ

Specifically, is it insanely toxic or something?

    Probably not more insanely toxic than other paints, etc. Home Depot stocks it for $19.97

    After seeing the video, I bought some. 'Not sure what I'm going to put it on. I was thinking my mountain bike. I mean, wouldn't it be great not to have to clean it after biking through mud and gloppy horse manure? But then I saw a blog entry that it doesn't stay on bikes very long, and it's a pain applying it to avoid the parts you don't want it adhering to. So maybe my dress sneakers will get the first treatment.

    It turns out the hydrophobic properties of the coatings on oil well drilling bits are more important than their coefficient of friction. My nephew spent a summer interning at Baker Hughes and one of his jobs was looking at the angles the edges of little water droplets made on various coatings, which is how they evaluated a material's hydrophobic property. One of the things he mentioned to me was that lotus leaves are super-hydrophobic. Nature accomplishes that by the microstructure of the leaf surface, they're sets of tiny columns of different heights. We discussed how one might replicate that artificially, I wonder if the Neverwet people have done something like that.

    Reminds me of the old joke about non stick frying pans and if the coating is so non stick, how do they get it to adhere to the pan?

    Not sure if I'd want to spray Acetone around anything I liked.

    I find it hard to believe they're reccomending spraying this on a PCB lol...

    This is a bit different but may likely revolutinize offices around the world. I watched a program a while ago about the guys that created it and was pretty amazed. http://www.ideapaint.com/

    The nice thing about it being paint is you can just repaint the wall every time someone screws up and uses a permanent marker instead of a dry erase one...

    Edit:

    Geez, I just checked out the price...that's a non-starter.

    Much cheaper to use smooth melamine coated board.

    Back when my shop did component level repair we used to clean PCB's with acetone. For the most part the plastics used in electornic components and circuit boards are immune to its solvent effects, and it is hydrophobic and evaporates very quickly making it a good solvent for depositing something else that is hydrophobic in suspension.

    Interesting, thanks for the info!

    it (acetone) is hydrophobic

    I think you meant hydrophilic. Acetone is pretty much completely soluble in water.

    The you tube viedos fo the pre rustoleum prototype shows that it works really well at first, then wears off after a bit. So we could water proof a cardboard box or pair of shoes today, but next week the affect would be gone. Perhaps other materials get "underneath" and unstick it from the surface its protecting.

    I wonder if the affect is more permanent in conjunction with rustoleum? I don't what to try this on. Ideas?

    Here's a pretty good review of Ultra-Ever Dry. I don't know how similar it is to Neverwet.
