[PSUBS-MAILIST] Potting

[Alan James via Personal_Submersibles]

Hi Rick,I have been putting a pvc glue an inch up the jacket of the wires and around the entry point of the jacket into the resin. I tested this to 2000ft.The reason I do this is because my first wire potting was a fail and WD40 ran down between the resin and the jacket without any pressure on it.I use a 2 pot heat activated resin they use on pvc inflatable boats. Hard to get hold of, but I think doing the same with silicone is better than nothing. The pressure cycling could compress the jacket and pull it away from the resin forming a path for the water.Alan

Built a form to hold the glue then put the wires in the holes, soldered the ends, put monkey S&”@t around the openings so they wouldn’t leak then poured the fiberglass resin in and it seemed to work.
