Epoxy Compatibility Question

Paul C

Recommended Posts

Hey Group. I’m sure this discussion has come up before but can’t find the thread in the archives. I recall reading not all epoxy brands are compatible with the old EZ-poxy system. What epoxy is recommended and compatible with EZ-poxy? Thanks…

Generally you can use any other epoxy on a cured epoxy laminate structure.  The bond becomes a mechanical bond which is not quite as good as a chemical bond but mechanical bonds are all over the airplane anyway unless you built them in one day.    :-)   Is that your question?    Take look at Gary Hunter's epoxy presentation here.  It is pretty informative.


And his epoxy reference table is posted here


Gary is an epoxy expert for Shell, I believe, and has always been the go-to guy.
