[PSUBS-MAILIST] data cable

[Alan via Personal_Submersibles]

Rick,
I don't exactly know!
After googling & asking advice I bought a number of glues that were 
supposed to be good for glueing PVC. 
I did a number of glueing experiments & found I could peel the glue off the
PVC with all products. I went to Lancer inflatables & asked them what they
used on their PVC boats & they sold me unmarked cans of a two pot heat 
activated PVC adhesive. I think he said it was a 3M product. 
It was fantastic, the PVC would tear rather than the glue peeling off.
Most wire jackets are PVC. I use PVC outside the hull & Teflon coated wire
Which is more fire resistant inside.
I looked at some professional rubber through hull fittings I had & saw that they
had a thin layer of rubber vulcanised to about an inch up the jacket from
where the head of the fitting was. I am copying this by coating the through hull
& the jacket of the wire with the PVC glue.
Doug Jackson did a series of videos on home made through hull fittings where
he had failure after failure & this lead me to look in to it a bit more deeply.
The water under pressure can squeeze between the insulation & wire, & the 
epoxy it is imbedded in, but with a layer of PVC glue over everything it can't.
I had success first test at 2000psi.
This looks a good product.

Any product they use on PVC inflatables should be good as it is water resistant 
as well as developed for PVC.
Cheers Alan
