[NSRCA-discussion] Fw: Epoxy Question

[Michael Ramsey]

If working with a foam wing skin (which is flexible like rubber) is a
little "rubberness" in the adhesive a good thing as long as the bond
isn't compromised? 
 
What's the alcohol to epoxy mix ratio limit?
 
Michael...

As I remember, Gray said something like, "If you use alcohol, your legs
will get all rubbery."  Or maybe he was talking about the epoxy.  Hmmmm.
Something fishy here.

		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.
