Which is the best glue for valves?

[edt]

do you need to purchase a 3M cartridge applicator to use it???

i was reading the spec sheet on the 3M structural adhesives, and I dont like the hardness of the 3M DP 8005. those 3M DP that begin with the number 8 are all acrylic formulation epoxies that bond together plastics, not sure they are meant to bond the type of polyurethane bladders we use. There is another DP product by the way DP 609 which is a polyurethane formulation not acrylic and it looks to be a lot softer which theoretically would be good for our kites. I don't think you need to buy all the pumps and stuff, as long as you mix it in the right ratio, I think most of them are 10 to 1.

I'd like to see someone try 3M DP 609

Check this out. 3M DP 609 has a working time of one minute and bonded in 9 minutes (full cure takes an hour but 9 minutes should be enough).

You could use this stuff be on the water faster than a slap on valve. The DP 8005 has a working time of a few hours and full cure of a day so it's about as fast as the 3M 5200 red tube. I have a full tube of 5200 left enough for a few hundred more repairs so I don't have a lot of motive to buy any 609 soon.

aquaseal is bomber in my experience. lasts a super long time, easy to work with. hardest part is weighting it down overnight, you need a large socket or piece of pvc or something that fits completely over the valve base and is tall enough to fit over entire valve stem so you can put weight on top of it. cloth tape (white athletic tape) is basically the exact right size but you need 2 rolls stacked up to be tall enough

original glue comes off easy usually with hot water and then alcohol to clean and degrease.

regluing an original valve is virtually free, just takes some time and effort.

Yeah, for the DP 8005 cartridge you probably need the applicator gun and the mixer nozzles. I already had these lying around from another project.

The hardness hasn't been an issue so far - the valve base can still flex. I'll inspect one of the repaired valves on the weekend and see if there's been any deterioration to either the bladder or the bond, but I suspect not.

Just had a look at the 3M DP609 specs - definitely a contender.

A couple of drops of Cotol-240 mixed with the Aquaseal accelerates the cure so that it's usable in about an hour. Spread it on both the patch material/valve and the bladder then let it sit for about 15-minutes or so until it gets gummy.Then stick the two pieces together and knead out the air bubbles. If the goo's the right consistency, they'll stay stuck together without the need to weigh them down overnight. Works great.

Cotol at Amazon

Been using a product called Vynabond which seems to do the job… No leaky valves on any of the repairs I've done.

Aqua seal, it uses moisture to cure, which is a bonus. if you take your time and use the methods mentioned above it is never coming off.

Thanx for info!!
Now that I carefully read up on carmo seal it is spect for soft pvc, not polyurathane, but I have used it with great success!
BUT.....Thanx to your advise....
I will get some aqua seal and add a little cotol as Kupono suggests; THANX FOR IDEA!
As for using new valves at 15 usd each , not for me!
I have re glued EVERY valve on every kite I have and 15 a pop is way to much!
I love forums, one can learn a lot quickly!
And to he who posted that once glued one is not able to remove and replace valves, simply not so with carmo seal, I have done it, simply clean carefully with acetone.
Now to find aquaseal here in Europe?
