Gluing Urethane to Neoprene with Aquaseal


As some of you may know I ran into a big problem when I tried to glue my suit the first time. I used a slow setting superglue and more or less once I pulled on the [sign in to see URL] neoprene ripped. Not good.
So I have a new suit. I have not glued onto that yet, but I did cut a bunch of samples from my ruined suit to test glues on.
I picked up a tube of aquaseal from my local dive shop. For this test I did not use the cotol-240 that came with it. I used roughly 1 square inch piece of urethane on a good size piece of neoprene. After 36 hours give or take( i do live in a low humidity environment) I can say this glue is holding fairly well. If I pulled on it fairly hard it would come of, as superglue would. But I have alot of flexibility in the neoprene still, which I never had using superglue. I am not saying this is the cure all for glue, but I bet this will work great for the knees, legs and arms where there is more flexibilty. I am not done with these [sign in to see URL] will keep you informed.

Re: My review of aquaseal using urethane and a triathlon wetsuit


As quickly as I wrote the last post, I decided to pull the armor off to test what happens.
It took some effort to get the piece off. All that happened was each side has glue residue on it. If it was superglue it literally would have torn the neoprene away from the fabric on the otherside. I used the thickest part of my old [sign in to see URL] far this is looking good. I move in one week. I will try it out at my new place with the cotol, which speeds up cure time and possibly with one of my knee pieces.
I also noticed that they make a contact cement for neoprene. I am going to order a can of that to see how it turns out. That has a faster set time.

Thanks for being our guinea pig. Appreciate it. emoticon

I'll be following this thread closely. My concern with Aquaseal has always been that the set time may be too long for one being glued up while wearing the suit.

you could also try something called urebond(sp?) from smooth-on. It's a glue used for , well, gluing [sign in to see URL]'t tried it myself, but when I start running urethane armor this is what I'll be using

Re: My review of aquaseal using urethane and a triathlon wetsuit *update*


I picked up the contact cement today by the same company. I followed the instructions. But it does not adhere to urethane. It stays stuck to it, but if you pull it, it comes off but leaves no residue. And it is thick and kind of messy.
But to glue down a latex suit it would probably work great.
Ok next I am going to try the cotol with the aquaseal again.
And I am going to try flexible CA.

Re: My review of aquaseal using urethane and a triathlon wetsuit


Thanks. I am just trying to find something that works for my scenario and so noone else ruins their Neoprene wetsuits. Superglue works great on thinner neoprene, but on something thick it just eats the suit away. Actually I think what happens is the glue dries brittle and leaves no flexibility for the armor to slightly move, so it rips the neoprene. Now granted, I now have some very viable solutions for fixing my undersuit should it rip again...

Re: My review of aquaseal using urethane and a triathlon wetsuit


Testing some superglue tonight. I realized I probably made the mistake of using too much the first time I glued my suit.
No conclusions [sign in to see URL] so far it looks like I will be:
Using Aqua Seal for the knees
Superglue and aquaseal for the legs depending on the flexibility I need.
And superglue for the chest and arms. The arms are really what I am most concerned about, but on a Triathlon suit this is usually the thinist and most flexible part of the whole thing.

Re: My review of aquaseal using urethane and a triathlon wetsuit


I used the aquaseal with the cotol on a test sample. I let it dry overnight.
It worked. That is the best way I can say it. On this same piece of neoprene I have a test sample with superglue. Both pieces are stuck on there fairly well.
So my idea of what armor to glue with what glue is holding true. The aquasure dries slowly so I really recommend glueing it while it is on a lifecast. Or do what I am going to do which is put on your undersuit. Mark where you want the piece. Take it off. Either stuff it with towels or something similar, lay down the glue on the inside of your lines, then lay down the armor on top. Hold for a minute or so to let the pieces "bond", then leave it for 3 hours. This is with the Cotol. Without it you need to wait 10-24 hours. Maybe longer.

Re: My review of aquaseal using urethane and a triathlon wetsuit


I'm sure there's an american equivalent but over here in england there's a neoprene based glue called bostik 2402, you can buy it in a 1 litre container with a catalyst to speed the whole thing up and it's apparently a contact glue so once it's on then it's stuck. it's also water proof and flexible, and from memory i think it said it's dry within an hour and fully dry 24 hours later. I've not got an understuit yet but i'll probably be opting for that when i do get one emoticon hope that helps.

Re: My review of aquaseal using urethane and a triathlon wetsuit


I just looked up Bostik. The issue I think you will find, as I have is finding what will stick to urethane. What it seems like Bostik does is the exact thing I tried with the cement last night. The cement I used was also for neoprene, but it did not stick to the urethane. See if you can get a small amount to try out.

Re: My review of aquaseal using urethane and a triathlon wetsuit


you could also try buying a small pint of urethane from smooth-on and some of thier "kick-it" cure accelerator and use that as the glue.

Re: My review of aquaseal using urethane and a triathlon wetsuit


Ok [sign in to see URL]. Man, will anything stick to urethane? Besides superglue. The test with the aquaseal with the cotol failed. Well kind of...
It stays stuck on yes. But due to the drying time and the lack of what I would say a truly strong hold on the urethane, I cant recommend it. If you have a latex suit I am sure you would have better luck.
Next is flexi type CA.
*edit* I was getting ready to go to bed and just looked down at my samples. How I did not see this I dont know. The aquaseal IS sticking to the urethane. When I pulled it off it actually removed the glue from the neoprene instead. How did I not see that??!!! Ok, more tests to come.

Re: My review of aquaseal using urethane and a triathlon wetsuit


Update...
I did not realize it but I had done one last test piece I forgot about for about two days. It was still aquaseal, without the catalyst being used. I just looked down on my desk/workbench and noticed what it was. So roughly after 48 [sign in to see URL] stuff is stuck on. Really stuck on.
I pulled on the armor piece and I was able to get it pried off, but for the first time it actually took some neoprene with it. So it worked. It holds to the urethane and to the neoprene. You just have to give it time. But unlike superglue, it should remain flexible. That is my big problem. The flexibility in the knees and arms. Superglue for everywhere else.
