Is it Sika Flex a good glue ?

Is it Sika Flex a good glue ? Does anyone already tried it ?
I think Aircommand already did it but I don't know the results...

What kind of glue is that? I have never seen it before.

It's a range of adhesives and caulks for marine applications, mostly PU like PL Premium.

See http://www.google.co.uk/search?q=site%3 ... F+sikaflex, http://www.google.co.uk/search?q=site%3 ... m+sikaflex and http://www.google.co.uk/search?q=water+rocket+sikaflex.

Consensus seems to be that by itself it can hold 100 PSI, or it can be used as a sealant in addition to PL Premium.

Thank you for the posts, it fails a 130 psi that is sad...

We have also tested an all-Sikaflex splice this week with the glue failing at around 130psi. The glue had given way, as both the sleeve and the bottle that was glued inside the sleeve were undamaged. The glue was left on both surfaces. This means that this glue probably should not be used for pressures above 100psi. We have a number of spliced pairs using this glue already made for the Acceleron rocket, so we will have to replace them with PL splices. We can still use them on other test rockets so we will hang on to them.
