Vinycol1520 or bostik 2402 for polyurethane (tornado) patch

[steve-ribnet]

Hi all.
Has anyone used bostik "vinycol 1520" 2-part glue on polyurethane RIb tubes before?

I want to stick some reinforcing patches to my tornado rib. It is tubed in the original polyurethane. The seams are intact but some of the over-seam tape is peeling. I know some reputable repairers would advise a full retube at this stage but budget does not allow

A google search reveals sparse information on exact glues for PU but suggest fleetingly that the usual hypalon 2-part glue "bostik 2402" should do, after abrading the patch area and cleaning with acetone.

Any views greatly appreciated

Cheers

I use Bostik 2 part Hypalon glue on a Polyurethane dinghy & it holds really well.

Thanks - nothing on the forum or internet on Vinycol 1520 though unless you can point me in the right direction?

I ended up using polymarine 2 part PVC glue on some parts and Bostik 2402 on others.
The polymarine was good for patches that needed some repositioning, as unlike the Bostik it doesn't immediately bond on contact with Polyurethane tubes. These repairs were clamped in place for 48hrs.

The polymarine stuff was no good for the underside of tubes that I couldn't clamp, where I used Bostik as it sticks on contact.

Patches with either glue seem to hold up equally well at present (fingers crossed)

I wouldn't use 2402 for polyeurathane i'd use the proper stuff! . The repair process is entirely different

Thanks for the link - do you know if the glue in the kit is the same as the Polymarine 2-part PVC/polyurethane? i.e. does it stick on contact like the Bostik stuff so you could you glue it to the underside of a tube without clamping it in place/ it falling off?

Guess I'll have to take the risk on the bits I've done in Bostik 2402, but for some of the repairs I just couldn't fashion a system of clamping the parts together long enough for the polymarine stuff to set, whereas the Bostik would stick on contact. It SEEMS to be a good bond...

Here you go...Ribstore PVC/PU 2-part [Contact] Adhesive Just need to make sure that the temp and humidity is controlled.

Is the MEK solvent still applicable to PU, or is it just for PVC?
The first link (IBS) lists acetone as the cleaner/primer for PU.

thanks

I used this as supplied by a friend who is a repair instructor for a large air,sea safety company.
