Hallo,
has anyone here an idea what adhesives could be appropriate for bonding fluorocarbon rubber gaskets? The bond should withstand 160 Degree Celsius (320 Degree Fahrenheit).
thanks in advance,
Volker

I personally don't, but these peole do:

Thank you. But I think UV-curing is out of the question since FKM gaskets are often filled (e.g. carbon black or barium sulfate) thus not permeable for UV.

I was thinking more about their cyanoacrylate line... Maybe a UV PSA would do the trick. What sort of bond strengths do you need? (and would you test at your limit temperature?)

Hi David,
No. The bonds should withstand 168 hours storage in mineral oil at
160 degree C and are tested at room temperature. Strength should be about 1.5 MPa (210psi). I don't know any cyanoacrylate that stand these temperatures.Volker
You ought to consider VITON(R)-based adhesive "Pelseal PLV 2100"
.. go to

there are some other questions:
what type of gasket is it, static or dynamic, what will be the other material for the bonding? will it only be used at 150°C or up from room temperature? how will the gasket be mounted?
how long should the adhesive work?...
How many Parts?
Perhaps special hotmelts (perhaps from Sarna Xiro) will work
with some FKM did seeral types of loctite work, they have one special type (850?) modified with NBR, this could be a solution
everal epoxys can be a solution....
the application leads here to a solution! Talk with the supplier of the gaskets (you bought some cheap ones from far east... so you have to pay the proce later....) and talk to the suppliers of adhesives... If it is a taylor made applicaton, tolk to both as soon as possible...
3M is very good in adhesives, even so loctite... DELOtwo years ago every of these Companies had solutions for bonding FKM uü to
150°C, but no one had a solution to solve the problem I worked on...nowaday I knpew the solution o the problems i had this time....
Michael I am not a bug I am a undocumented feature
have some fun... the additives in the oil will kill most adhesives
1500000 Pa that are 15 bar so the forces are not to big...so try hot melt foils ask Sarna Xiro...
Or ask TESA for an adgesive tape...
