Questions about epoxy safety

[scalewiz]

Looking for info...is there any danger to having epoxy resin inside a tank device. (Cured, of course). I was wondering if there was any danger of leaching chemicals if epoxy was used inside of a tank.

I don't know the answer, but I'll bump it so hopefully someone who does can see it and answer.

If you can avoid it then it would be better to do so.

Epoxy resins will leach into the surrounding medium (more so as the temperature goes up).

Not a great deal ( a lot of containers aluminum cans , flasks etc are epoxy coated ) but if you can avoid it .......

i wouldn't use any epoxy that wasn't at the very a food grade epoxy ,,,some of the catalysts used to make that cure can be be very toxic,,,super glue would also be a bad choice

look for food grade RTV silicone,,

Thanks. I know there is a lot of discussion about epoxy leaching in water systems, can linings, etc, but my brain still can't get completely wrapped around it. Some of the chemicals in the flavorings may really be bad against the epoxy, but who knows. I am sure the exact epoxy composition will have a lot to do with it. Don't wanna start inhaling these BPA thingies.

What I am really wanting is something to use as a seal inside my CE2 tanks. I would like a sealant that can flow and then harden like epoxy or something and, of course, be safe.

Clear Silicone ?

Still not comfortable with leaching issues. I think I'll try epoxy (need the strength) with a silicone cap. Maybe the silicone will keep the liquid away, but I will watch for a violation of the silicone sealing. I'm trying to do some mods to my Stone/Cartzilla tanks to eliminate leaking through the bottom seal.
