Hello,

I am making temperature sensors with an IC sensor enclosed in a 6 foot
piece of 1/2" diameter stainless steel pipe.  I need an epoxy to fill
the pipe to protect the sensor, displace moisture, etc.  I have been
checking prices on potting epoxies and it seems they are considerably
more expensive and difficult to locate than the standard hobby shop
variety, especially when only needing approximately 1/2 gallon.  I am
looking for opinions on whether I should go for the potting epoxy for an
application like this or whether the standard variety epoxy would
suffice.  The sensors will spend long periods of time (months to years)
at temperatures of approximately 200 degF.  Thanks for any ideas.

Nick
