loctite two part epoxy: suitable for reefs?

[astroboy]

Hello.

 

I'm gluing together some plumbing parts that will go into my sump, using Loctite Quick Set Epoxy. It's one of those epoxies that come out of a double plunger that you mix together. Does anyone have any experience with this stuff; will it kill everything in my tank?

 

On the directions it says:

 

"Will not bond to polyethylene or polypropylene products, or prolonged immersion in water"

 

Hard to tell with the poor grammar, but this sentence seems to imply the epoxy will eventually leach into water....

 

Thanx,

 

Mark

I just used PVC glue from Lowes, costs about $5 a can and comes with primer and glue.

yea, I'm not sure why you're using epoxy for plumbing parts. All PVC should be glued together using PVC solvent. I dont think I'd use that epoxy underwater. Stick with a super glue - cyanoacrylate - if the solvent won't do what you want.

Well, to be more specific:

 

I want to make a chemical filter out of one of these clear plastic containers with a white screw top: in this case, a one-liter container that held seachem ph buffer. I want to attach the output nozzle from a rio 600 pump to the white cap, I'll drill holes in the other end of the container and fill with chemi-pure. (A crude version of this idea works amazingly well with activated charcoal).

 

Super glue doesn't work well in joining the nozzle to the cap, neither does plastic cement, (the kind you use on airplane modes), nor does the stuff you use to cement acrylic together. So, I thought I'd give loctite epoxy a try but I'm having second thoughts about possible toxicity. Better safe than sorry.

 

I guess enough people in the hobby fiddle enough with PVC that PVC cement must not do any harm. Does any know otherwise, or have any other advice? It would be much appreciated!

PVC cement doesn't do any harm, but won't work for what you're doing. It's a solvent that chemically welds PVC and really doesn't work for non-pvc items. I bought some glue from HD, I think it was loctite brand, that was for gluing acrylic and listed as aquarium safe. I think that stuff will work for you. Can't remember exactly what it was called off the top of my head.

I think this is the stuff I used:

Try some aquarium sealent if nothing else works, that may work for what you are trying to do.

Thanks Brian. I'm doing a run to HD this evening so I'll pick some up.

 

I have some aquarium sealant, but I'm very sure it won't work for what I want to do....

 

Thanks everyone!

Astroboy,

I have used the Loctite quick set in the plunger that you mentioned. I used it to mount powerheads onto algae magnets. It worked fine for that. I would just let it cure well before putting it in the tank to allow for it to fully off gas first. I don't think you have much to worry about as you wouldn't be use that much of it.
