I tried to follow the instructions for sealing bulkhead penetrators with the Thixotropic 80A potting compound, but it seems I must have messed something up. The platic has cured quite soft, like a gummy bear.
What did I do wrong?
I used an epoxy squeeze gun and mix tip, and I squeezed a little out first, so I believe the mix is good (but I could be wrong).
I know winters in California are epoxy nemesis 100% humidity and 10C. Should I do this with the heater on or wait until warmer weather? Will they ever finish curing if I put them in the oven?
Edit: move to the correct topic categroy. Also a little more about my application
I am connecting some control lines from the control pod to the battery pod with a spare length of the yellow tether cable. The epoxy cured soft, and also it fails vacuum. Replacing my cable penetrator with a blank gets it to pass vacuum so I am sure it is the cable penetrator.
It passes vacuum and appears to be the same stuff as is sold on the webstore. My technique was the same as the video for potting the power cable, though I did add some teflon tape around the wire on the bottom so resin doesn’t get all over the floor or on the threads. I may not have gotten enough resin below the outer jacket to seal around the individual conductors.
Does the cable itself leak air in between the wires? Should I have done a ‘second-op’ of turning the penetrator upside down and potting the back? Or is my technique flawed and I should practice a few more times how its done in the video? Is the technique for potting the yellow tether cable the same as for potting the power cable?
