Subject: [TN] Off-Topic - coatings for airplane-home
> Definitely off-topic, but interesting . . .

> I have a friend who is making his new home out of a 727 airplane (see
> www.AirplaneHome.com <http://www.AirplaneHome.com> for details). He is
> investigating coatings he might use to "paint the house", and has rejected
> his first choice (Kapton) when he found that it deteriorates when exposed
to
> UV and Oxygen (I think that was what it was). Since I've seen some
amazing

front

> Hot dog, thanks very much. I've always been very fond of RTVs - they seem

> Teflon. I've never in my life seen any evidence of any form of

> The timing is quite good too in that I've been thinking about coatings

> I've been pressure washing again in the last few days, and I've noted
that,

> adhesive bonds, is unreliable. When the pressurized water is forced onto
> the
> chromate at its most aggressive (with the wand within a cm or two of the
> surface), the chromate sometimes get fainter and fainter as if they're
being

> abraded off. But they never peel. That's impressive.
>
> And that's what I'd like in a coating - a true chemical bond, so that it's
> literally part of the metal, not just a layer over the metal. Well, that,
> plus absolute immunity to UV, chemical weathering, and every other factor
> that makes a coating just plain perfect.
>
> Teflon's been on my mind too. It's extremely stable of course. But I'm
not

> sure what the nature of it's bond is, or what the economics are - I need
to
