Replace the Feedthrough
Review important points prior to any replacement procedures.
1. Thoroughly clean the replacement feedthrough and the inside of the
feedthrough port with deionized water and a Scotch-Brite type scrub
pad used for Teflon-coated pans.
HAZARDOUS CHEMICALS!· The primer and adhesive used in
this procedure are caustic and have hazardous
vapors. Be sure you are using them in a well
ventilated room and that you protect your clothes
and skin. You MUST wear side shield safety glasses,
rubber gloves and a protective smock when using
RTV adhesives and primers
2. Using the containers and epoxy in the feedthrough kit, mix in the
proportions shown below. Use a gram scale for precise
measurement. Gram scales can usually be obtained at the customer

Do not mix more than can be used during the 40 minute
pot life.

4 grams resin (Part A) to 1 gram
activator (Part B)
Pot Life:
40 minutes.
Cure time:
24 hours at 25º C or 8 hours at 40º C.
3. Cover the feedthrough port so that you can pull a vacuum in the
chamber.
4. Mix the resin and activator thoroughly and de-aerate in the chamber
(using the Vacuum/RF test) for approximately 10 minutes until all
frothing ceases. Be sure to place the epoxy containers in the chamber
