Alright so it will handle contact with room temperature ethanol.
Did you ask what effect nearly pure ethanol in vapor form and at high
temperature at the same time would have?
I am asking because I have had numerous failed experiments using
epoxy based products. There are very hostile chemical conditions
present inside of a still operating at normal temperature. Ethanol
is the main product of the fermentation process but not the only one.
What happened in my circumstance was that the epoxy applied and cured
according to the package directions. The after a few product runs,
the substance broke down into subcomponents and came "unglued" and
then that gunk plugged up everything else from packing material to
product out take needle valves. You may have better luck if you are
planning on using it on external applications. However I had one of
those become a less than permanent arrangement also.
My failed experiment results gave me the conclusion that any
solution that doesnt involve glue is a better solution. I am wishing
much better results but am advising against using it on internal
To silver solder a connection requires a propane or MAP gas hand
torch a small container of solder flux compound (with brushes) and
also the silver solder its self. I purchased both at a plumbing
contractor's supply house on a cash purchase basis. The solder was
more expensive than the torch head. It set me back about 30 US
Dollars for a one pound (weight) roll. But you use so little of it
that .. the roll will last me for years of modifications.
