I found a what they call liquid glass. My understanding is that it is liquid resin.
You drop it / paint it on the circuit and it forms a protective layer on top.
The problem or rather my question is that in forming it goes up to 90degrees.. obviously once formed it cools down.
Will it destroy any circuits / capacitors or any other parts on my motherboard in the formation process due to heat..?? :confused:
I'm only thinking to put it underneath the armaflex, around the cpu as i can't find any pcb varnish and i am not too keen on using nail varnish
The mobo is P5WDG2.
any advice appreciated
Solder is done at 130c i think on these mobos

you should wonder if it expands any as it starts cureing. if it does it may rip or stress components on the board.
try that stuff on a TV remote controll or something, then put it in the freezer for a few hours followed by putting it in the sun, and see if it has any thermal stress issues

I am sure it doesn't have any thermal stress issues; at least that is what the manufacturer has advised
I'm only really concerned about the fact that it will get up to 90 degrees and if that would destoy any components on the mobo..

you can used rubber cement below your armaflex insulation. its easy to remove and will protect your motherboard just as well from condensation as nail varnish would.

What you are talking about is acrylic resin. It doesn't get to 90 degrees when it is applied thin. The temp increase is from the amount of catalyst used. When you are doing a cast mold you use less because it cant get rid of the heat and will crack. When you cover something like one of the shiny clocks where it is thin you use more catalyst to offset the heat being generated. Any more questions?
