Epoxy does not cure

Hi folks,

I have followed this tutorial to do the potting for a coaxial cable. But the epoxy never cures and is still liquid even after 2 weeks in room temperature. Does anyone have any idea for possible reasons? I’d really appreciate it.


I had some problems with it too at first. What is the room temp and how are you mixing it? My issues were temp related in winter and I figured it’d just take a little longer being a little colder, but it’s not very linear and the cure time ramps up to infinity when you step a little too far outside the range.

Seems like a ratio issue.

A little trick to make it a bit better looking results, use electrical tape around the perpetrators.
