[NSRCA-discussion] Fw: Epoxy Question

[Karl G. Mueller]

Did anybody ever try a commercially available "Epoxy Reducer" ?

  That is very true, however, it depends on the amount of alcohol used and
strength required.  I routinely use thinned 5 minute for fuel proofing,
never on a structural joint.

    Didn't the master say that is not good idea to use alcohol to thin
epoxy?  I could be wrong since my memory is bad.  Anyone remember?

      Well folks,

      Here is a preliminary finding...Considering the fact that I probably
skewed the results by stirring the mixture to keep it incorporated, and the
5 minute epoxy mixture I used has only been curing for about 60 minutes, I
found no detectable loss of weight on a Pelouze PS20DL digital postal scale.
I will try to attach a pic of the weight of the cup, stir stick and mixture.
      The cup and stick weigh .5 oz, with the remainder being the mixture.
One thing you will see is that stirring the mixture makes a gelatinous
mess...

        OK,  I'll take a stab.  After the alcohol evaporates you would have
the same mass or weight of epoxy that you started with.  AND to reiterate
what I learned from the Master Fowler, thinning epoxy, if I remember right,
changes the molecular structure weakening the mixture.  It will also cause
the epoxy to shrink over time. BTDT.

          Breaking news.  Here's something from Mike Harrison that will be
of interest to the list.

          Ok, think about this, take 1 oz epoxy and thin with 1 oz alcohol
(91%).?  After curing how much do you think it weighs and tell me why.

          Mike
