epoxy on atty connector

[redgirl]

I'm not a modder by any means, but I have a Fistpack that the atty connection keeps coming loose. Basically, it's not completely coming off, but just is wobbly. I took the existing epoxy off around the atty connection and went out and bought some Devcon 5 minute epoxy in clear. Now it has turned all brown from the juice and is starting to deteriorate again. I don't know if I didn't let it set long enough, or if I should use a different type of epoxy. Any advice on how to make a sturdier connection?

From what i have read alot of folks in here use JB weld for there mods. Pretty sure they dont make a clear version of it though. When dry it is a grey color. They make a quick set version of it that dries pretty quick. Also i believe they claim it is non toxic when cured, so thats another good thing about it.

I use JB Weld or JB kwik just follow the instructions and set up times.

Make sure you followed the set time. PG/VG can deteriorate the bond if it has not fully set. Be patient.
Devcon has worked fine for me, when I let it set properly. The times I got impatient and started vaping, the epoxy broke down like you described.

After mixing and appying, to speed up the epoxy curing procces you can place the unit near a light bulb. Gentle heat (about 4 or 5 inches away from bulb) will hasten the cure.

Thanks, everyone! I think I will try to scrape off the existing stuff tonight and let it dry at least overnight. I hope that no juice has seeped into the unit, but I'm a little afraid to open it for fear of breaking it.

To clean up old juice use PGA alcohol or in a pinch rubbing alcohol, just let it dry. Also ruff up the area were the epoxy will be to create a better bonding area. Good luck

Awesome. I just got the old epoxy up, but I scratched the unit a bit. That was tougher to get off than the original!

Fantastic!
I was going to post this exact question today.

After checking those links for JB Weld or JB kwik, is there a difference between how well they
will work in fixing a wobbly atty connection?

Thanks!
Lori,

Lori,

There is a diffrence between the two in tensile strength and setup/cure time and max temp. JB Kwik setup/cure time is about 4 min/4 hours and tensile strength of 2100 and temp of 300F. Where JB Weld setup/cure time is 4-6 hours/24 hours tensile strength of 3960 and temp of 500F. The biggest diffrence we are worried about is the cure time. so we can get back to VAPING

Thanks for the explanation. Now hopefully I can find it at my hardware store.... Sucks living in a
small town.

 

[happest]

Look for it at your local wall-mart or Ace hardware store

JB Kwik can be found most anywhere....I saw some in a convience store this week. Make sure you:
Clean both surfaces
Rough up both surfaces (epoxy needs as much surface area as possible for optimum hold)
Dispense the correct ratios and thoroughly mix them
Let it set before using (overnight)

JB Weld has iron in it, to make it more metal like and be drilled and sanded. It doesn't mean it will adhere better to plastic or be more e-liquid resistant.

All epoxies will eventually lose their bond and soften when soaked in e-liquid.

I'm assuming this is a version 2 (the walk-through). The weakest point of the build was the connector was epoxied. I tried a bunch of different epoxies and none of them withstood the test of time. The combination of repeated heating and PG always ended up causing an eventual failure.

The final solution was to switch to a mechanical connection (adaptor with nut and loctite to permanently secure it). This solution turned out to be extremely reliable.

Good luck

the one I'm playing around with right now is a 2 part epoxy resin that's heat and alcohol resistant is foodsafe and is used as a bar topper called envirotex lite .
It's kinda advanced to work with and flows like syrup so you have to make sure where you're putting it is blocked off well... but it dries solid and clear ( 72 hour total drying time)...

worked extremely well in a box mod I did...all connections in that side of the box are encased in clear acrylic now..

 

[sahara4evr]

I'm glad someone asked this question. I bought a box mod and the atty connector becomes loose after I vape awhile. I have to let it cool down before I can remove the atty or the whole connector comes out. I'm not handy at all and I wonder if this issue is important enough to send the PV back to the manufacturer or just continue as I've been.

that is odd when they state that it can be used as an electrical insulator? doesn't iron conduct electricity? I think so!!! time to find a new epoxy to use

It's not conductive.
