comments from West are interesting:</span></font></p>
<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>“There are epoxy-based products
specifically designed to penetrate and reinforce rotted wood. These products,
basically an epoxy thinned with solvents, do a good job of penetrating wood. But
the solvents compromise the strength and moisture barrier properties of the
epoxy. WEST SYSTEM epoxy can be thinned with solvents for greater penetration,
but not without the same compromises in strength and moisture resistance.
Acetone, toluene or MEK have been used to thin WEST SYSTEM epoxy and duplicate
these penetrating epoxies with about the same effectiveness. If you chose to
thin the epoxy, keep in mind that the strength and moisture protection of the
epoxy are lost in proportion to the amount of solvent added.” </span></font></p>
<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:black'>“There is a better solution to get
good penetration without losing strength or moisture resistance. We recommend
moderate heating of the repair area and the epoxy with a heat gun or heat lamp.
The epoxy will have a lower viscosity and penetrate more deeply when it is
warmed and contacts the warmed wood cavities and pores. Although the working
life of the epoxy will be considerable shortened, slower hardeners (206, 207, 209)
will have a longer working life and should penetrate more than 205 Hardener
before they begin to gel. When the epoxy cures it will retain all of its
strength and effectiveness as a moisture barrier, which we feel more than
offsets any advantages gained by adding solvents to the epoxy.”</span></font></p>

font-family:Arial;color:black'>1. "Thinning the epoxy saves no
weight by evaporation. There is virtually no evaporation and no weight
loss-a big time erroneous assumption on my part. So if you mix 2 ounces
of epoxy and add 2 ounces of thinner and put it all on the airplane, you have
added 4 ounces to the airplane. "</span></font><font color=black><span
style='color:black'> <br>
<br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>After seeing the real question I expected a
weight increase of at least 9% (how much water in the mix). If you put 1oz (by
weight) of solvent in 1 oz of epoxy, and apply it as a coating , thin, you will
eventually end up with 1 oz of epoxy. Mike, your solvent got trapped, and now
it will have less adhesion, less tensile, Compression and flexure strength, and
will now shrink slowly as the alcohol exits the cured epoxy, over a year or so
(see Wayne's answer).</span></font><font color=black><span style='color:black'>
<br>
<br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>None of the solvent's listed will react with any
epoxy blend. Exotherm is negligible when applied as a thin coating, but
significant in mass. The ability to have the solvent evaporate out of the epoxy
coating is directly related to the mixed viscosity of the neat epoxy blend and
the cure rate of the epoxy. Those of you who ran experiments with 5 minute
epoxy reported bad results because of high viscosity and fast cure rate.The high
viscosity (even Mike's blend is apparently too high) will cause a skin effect
where the solvent evaporates from the surface first, creating a high viscosity
skin, then the epoxy starts to cure increasing viscosity even more, thus
trapping the solvent. Using fiberglass makes this even worse. MIKE- in one year
from now your wings will weigh less.</span></font><font color=black><span
style='color:black'> <br>
<br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>So it sounds like the the Pattern Dudes of the
world need a solution. What AeroSlave can do is provide a super low
viscosity epoxy for sale. This will be 100% solids (which means NO solvents).
Chances are, as a mixed epoxy, the viscosity will be lower than even blends
with some solvent in them. This can be used to apply fiberglass to wings or as
a general laminating resin.</span></font><font color=black><span

font-family:Arial;color:black'>How much interest would there be for such a a
product? It would probably cost about $50/ quart, $25/ pint. It would
absolutely require an accurate scale (+/- 1 gram) to WEIGH the epoxy and
hardener into the appropriate mix ratio. AND I offer no warranty, simply
because you guys are the biggest bunch of experimenters in the world, and I
cannot control, nor anticipate how this could get screwed up.</span></font><font

some of you have educated me on this issue. If I may, I will share what I
have learned.</span></font><font color=black><span style='color:black'> <br>

</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>1. Thinning the epoxy saves no weight by
evaporation. There is virtually no evaporation and no weight loss-a big
time erroneous assumption on my part. So if you mix 2 ounces of epoxy and
add 2 ounces of thinner and put it all on the airplane, you have added 4 ounces
to the airplane. </span></font><font color=black><span style='color:black'>
<br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>2. The properties of the epoxy are
changed-it becomes rubbery.</span></font><font color=black><span
style='color:black'> <br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>3. Changing the properties is not an issue
regarding finishing the airplane(painting)</span></font><font color=black><span
style='color:black'> <br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>4. Using thinned epoxy is fine for
applying glass cloth.</span></font><font color=black><span style='color:black'>
<br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>5. I have tried MEK(epoxy thinner),
denatured alcohol, 91%alcohol, acetone. My preference is denatured
alcohol because it is the safest and most economical, I think. I thought
MEK would be the answer. It is the worst of the bunch. </span></font><font

</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>6. The best way to glass surfaces is to
thin the epoxy and apply as sparingly as possible. A way to do that is to
apply and wipe off excess with paper towels. </span></font><font
color=black><span style='color:black'> <br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>7. It is almost exactly 2 ounces to glass
a wing panel complete, so 4 ounces for a whole wing. About 2 ounces for a
stab. Properly done wings and stab glassed and painted is 2-2.5 times the
weight of monokote. </span></font><font color=black><span
style='color:black'> <br>
</span></font><font size=2 color=black face=Arial><span style='font-size:10.0pt;
font-family:Arial;color:black'>8. A second thinned coat of epoxy on the
glassed wing is .75 ounces each wing panel-1.5 oz total.</span></font><font
