Bostik 2402 & Strongan Duotex

[clintog]

Hi all, First of all Id just like to say after extensive hunting I can confirm this forum is head and shoulders above anything else out there. Well done -

I have an issue. I have recently purchased a Zodiac Cadet 340 S. It's in NZ where I will use it as my land based fishing craft. Im short IRB's are the best small boat for this. However there is one small drawback, rocks - which inevitably lead to punctures.

To get around this lots of guys glue sheets of 3mm neoprene insertion rubber to the sides and bottom of thier boats.

Here's the question. Is Bostik 2402 suitable as a bonding agent between "Strongan Duotex" and neoprene?

In this - http://www.farnell.com/datasheets/311054.pdf - document it states

"IMPORTANT: It is not recommended that BOSTIK 2402 be used with plasticised PVC because of the possibility of plasticiser migration"

Is Strongan Duotex plasticised?

Any other handy hints appreciated.

Cheers -

Yes is will be - unplasticised PVC is not particularly flexible. Is 2402 Hypalon Glue ? (I think it is from memory) In which case is there not a different product specifically designed for PVC?

Hi, thanks for the quick reply. Yes Bostik's 777 is a PVC glue.

However I run into the same issue as that doesnt say its a rubber (neoprene) glue for the other side.

Any ideas?

Use two coats of pvc adhesive to the pvc and allow it to cure fully. Now you can use 2402 to join the pre-glued pvc to the neoprene. The pvc adhesive prevents the plactisizer migrating into the 2402. As usual, search ribnet, it's all been said before and so has the method of joining both types material. Good luck with it.

2402 is for hypalon Neoprene only , you must use a urathane glue for PVC coated fabrics ,if you can't find any in your area email me I'll send you a quart

Thanks for the reply - I cant find any thread where someone has tried this. If the 777 and 2402 dont have an adverse reaction to each other this would work well.

Thanks - But we run into the same issue of urathane glue to the other surface - rubber.

This probably covers it quite well:

Hey JW - I just read your post kindly resurrected by polwart. Would you suggest using the 2402 as the bonding surface or the PVC glue?

By that I mean after you have coated both the PVC and Rubber would you -

1) Apply 2 or 3 coats of 2042 to the coated PVC or
2) Apply 2 or 3 coats of PVC adhesive to the coated rubber

- then make the final join?
