Using Bostik clear bond on Hypalon?

SpearRib · 18 January 2015, 01:43

What would happen if I used my bostik clear bond that I had for my previous PVC boat on hypalon? Just a therotical question. Of course I wouldnt use it in structural areas but would it eat the hypalon?

No, It probably wouldn't do anything to the hypalon. Probably wouldn't hold, either, at least not for long.

there is another single pot they call Super Contact Bond. cant find it on the international site but if you google it you will find the specs.

sounds pretty heavy duty.

Why don't you just get some polychloroprene adhesive?

ill see if i can find that in a cheap tube in Aussie.

not sure what bostik super contact bond is made of.

dont want the hassle of 2 pot or the expense for such a small insignificant flap.

Is polychloroprene the main ingredient in 2 part glues as well?

It's the posh name for Neoprene (i Think)

Hassle? Put the approx amount you need in a small container, add a few drops of the modifier (the 2 parts are not like epoxy; the additive makes the glue more chemical resistant, rather than being a hardener/cure agent), stir a bit, and apply.

Not like it's an hours long science experiment. It adds may 20 seconds to the process. Not much for a bond that actually holds up (which the single part adhesives are notoriously bad at.)

i meant more the cost $60 vs $6.

Its a non structural small lift that i cant see moving.

I know someone will say well you can always use the left over $60 glue later, but we have other plans so dont think we will. Also money is tight at the moment.

Of course if there are no single pot glues that will hold a non structural lift down then I wont bother, but I just wanted to know if there is single part glue for hypalon.

I understand the money thing, believe me.

As to the using later, well, most glues have a shelf life of a year, unopened. Opened, considerably less.

That said, you also need to consider the ramifications of spending a little money on something that *might* work, vs. spending more on something that will likely work, and balance the whole thing out. In the end that one's on you.

Check for Polymarine locally.

They sell a polychloroprene 1-part.

Found it on a .AU web domain for $26.

It's basically 2-part adhesive that is premixed and bottled.

Apply 1 coat, wait 5 min
Apply 1 coat, wait 3 min
press & burnish/clamp

I saw that product, its from the UK? Unfortunately I cant get it due to lack of credit card. Looks like you guys get lots more RIB options than Aussie.

Essentially what Im trying to fix is the first layer of Hyaplon that has come off a small hypalon tape edge in a really non stressed area that gets no water. The hypalon top layer of the material sandwich has lifted maybe 1cm long. I think its neoprene the next layer of the "material"?

Also it would be impossible to keep the material seperated to make 2 coats like with 2 part glue. Hence why I want to know what 1 part glue is ok for this kind of use. I just want to know which glue wont eat through the material.

Hence why i dont want to spend $60 when I know its really unimportant but still annoying to me.
