Re: [PSUBS-MAILIST] Anti-Condensate Coating

[Jon Wallace <jonw@psubs.org>]

Hi Jim,

There's quite a bit of material on the web regarding anti-condensation 
coatings, although I hadn't heard of this until you posted your email.  
I found http://www.chemicoat.com/ which has the following on it's website.

"AQUABAN is a permanent, water based coating which when applied to a 
thickness of 1/32", will prevent condensation by absorption and 
desorption. This action widely disperses water vapor and releases it 
back into the atmosphere before dripping occurs. Thus the coated surface 
remains dry to touch."

In a plant or yacht there would be transfer of air which would make the 
coating very desirable.  In a small enclosed area like a submersible 
cabin, the water vapor still would have no where to go as it was 
released back into the atmosphere.  If it absorbs a certain amount of 
vapor before releasing it back, then that could be beneficial if the 
absorption properties are greater than the amount of vapor produced.  If 
so, it sounds like the coating could possibly be used as a build-in 
"dehumidifier".  And if it has insulating properties, that would be an 
additional benefit.
