Jarrett,

I'm building an ES and used Hysol EA 9339 for the H stab, wings,
ailerons, elevators and flaps.  We mixed full quarts at a time when
closing the wings and just mixed it right in the container using a
paint mixer attachment on a hand drill.  I kept the temperature above
77 degrees for at least the first 12 hours each time for the initial
cure.  In the winter, I used a closely monitored propane infrared
heater in my garage.  There were no sticky surfaces after a couple of
days curing.

They do allow a post cure temperature of up to 180 deg F.  One hour at
180 F would give complete cure.  It would take longer at lower
temperatures.

I recommend that you try contacting Loctite directly.  My wife was able
to talk to one of their chemists over the phone about the shelf life,
so they may be able to give you an answer too.  Their phone number is
925-458-8000.   www.loctite.com  Give them a call and see what they
say.


(BTW) According to Vern, Hysol EA 9339 is not in production any longer.
 Apparently, Lancair was the only customer buying it.  Lancair now is
supplying Hysol EA 9360.  It has somewhat better properties than the
9339.
