Need Extra Strong, Water Based Glue

I was looking for something recently for wet conditions outdoors. I haven't used it, but the Liquid Nails Fuze It was the best looking thing I could find on the internet - couldn't get it locally. Underwater test in this promotional video (but is it real?):

The one my landscaping supplier recommends for outdoor/wet conditions is Loctite PL Premium - I don't know if it works underwater but the Loctite PL products did well in these tests:

There's a good discussion of PL use for boats here. Last comment maybe most informative - it can be useful but not as durable as epoxy in the boat context.

Maybe they'll let you test some....

This stuff is really good, but it takes a long time to cure....

You’ll have to give us more information than that. I searched “Fulloprene 330” and the only thing that came up was this discussion.

Fusor Direct to Metal Sealer Adhesive

You want a water resistant adhesive.

This is an example of what's out there.

Disclaimer: I have never used this adhesive but you need a two part adhesive, not anything called glue.

You don’t mean water based glue, correct?

Water soluble until cured...(?)

Epoxy in 2 parts, when nothing else works, or JBWeld

I suspect that your title is a mistake! Unless I'm badly mistaken, and as suggested by a couple of previous posts, any glue (adhesive) that is water based will not last long under water.

In my experience, the most durable water resistant adhesives are all two-part products that must be mixed at use (commonly known as epoxies). I've had good luck with several different ones.

Just this last week, I had a tooth filling that was done with a polymer that is hardened by the application of UV light. Obviously, that substance must be very water-resistant! Between advances in the polymer and advances in the UV light sources, these compounds have become much more useful. This filling was activated by just 30 seconds of UV light from a hand-held UV "flashlight" (definitely NOT just a $10 UV flashlight). It might be worth investigating...

My experience is the Henkel/Lokite folks are very helpful, or at least the guy that covers our area (NC/SC) is. You can probably take your application directly to them and get good advice.

Yes, My description was in error. It does NOT have to be water based.

I have contacted all of the distributors of the products mentioned and am awaiting replies.

Yes, I need the glue to adhere strongly to all three materials.

Thank you all as usual, for your input. I'll await what the manufacturers say.
