<DIV><BR></DIV><BR><FONT face=sans-serif size=2>First, NEVER dilute epoxy
adhesives with anything. If you do you will end up with the epoxy plus the
crap you put in as a finished product resulting in an incomplete reaction
which equals lower strength, lower temperature resistance and lower chemical
resistance. This is not "glue". Second JB weld does not come close to
the temperature requirements of an exhaust system. Whats epoxy does? Not too
many that cure at room temp. Metal (aluminum powder) does not increase the
temperature resistance, only keeps the adhesive from softening as much as a
non filled version.</FONT> <BR><FONT face=sans-serif size=2>The best bet for
your application is Hysol 9394. This adhesive cures at room temp and then with
an elevated post cure can withstand 350F continuously. Heres how to get
some free........everyone remember this-trust me it works.
</FONT><BR><BR><FONT face=sans-serif size=2>First make up a fake company name
( or if you can use your real company name). Log onto www.dexteraero.com
get the contact info closest to where you live. Call and say that you
are investigating high temp epoxy adhesives and are bonding and conducting Lap
shear tests at 300 and 350F. Your analysis says you need about 1000 PSI of
shear strength at 330F-ask for Hysol 9394. You are bonding<B> 3 different
times</B> and only need about 100 grams for each time. They will send you 3
pre-weighed mixing semco cartridges. If they start asking you questions that
you cannot answer prentend to be new on the job and where told to do this, or
better a supply chain management person-they buy everything without knowing
anything......Hysol will send these as free samples. If you are worried than
you can by these cartridges from from the local distributor for about $35 each
or get a quart for about $75.</FONT> <BR><BR><FONT face=sans-serif size=2>Now
if there is a Hysol rep on this list then NEVER MIND.......It all for the
promotion of pattern.......<BR><BR><BR><BR>Gray Fowler<BR>Principal Chemical
