Polymarine/Bostik glues for hypalon

[BogMonster]

While sitting on the potty browsing through the Transmarine catalogue I got while I was away, I see the Polymarine 2990 hypalon glue is available in both a 1 pack and a 2 pack variant.

Is the 1 pack any good?

I've also just bought a single tube of Bostik "inflatable boat adhesive" (said to be suitable for hypalon) while I was out looking for superglue gel in the shops, again this is not a 2 part adhesive.

From what I've read on here I understand the 2 pack is the best but is there much difference - what would you use the ordinary "tube of airfix glue" version for? It seems that it would be easier to use since the 2 pack stuff seems to go "off" and get quite thick within just a few minutes, though it does stick like sh** to a blanket

Just curious really, I have no need to get any tube stuff as I have 10 tins of 2 pack to play with for my repair jobs but I wondered what the pros and cons were...

Stephen: if the Polymarines stuff for hypalon behaves in a similar manner as thier PVC glue then it will cure MUCH better with the "activator". From what I've seen when used on its own it doesn't really properly set.

As to Bostik, the one part glue is OKish (part no. 1758 or something similar) but its only really good enough for a temporary quick fix. Even for the job that you are looking at on your tubes I'd recommend going for the Bostick 2402 - it really is good stuff. Its probably been said in other threads but preparation of surface is REALLY important. From the few repairs I've done getting the initial surface prep'd well makes a huge difference to the final bond strength.

Good luck with the repairs mate

Cheers, just wondered what the disadvantage of the single pack was, given that it is easier to use, but I guess the answer is bond strength then....

Always use the Bostik 2 part, either 2402 or the NE486, none of the other glues come close.
