Static Mixer - Introducing Air Bubbles

[esteess]

I want to use a static mixer nozzle to mix hardener with an epoxy resin that both are formerly degassed in separate containers.
The question is that is the mixing in the nozzle going to introduce air into the polymer mix and all degassing process done will become pointless?
It is well known that excessive disturbing degassed mixture can bring air back into the substance (like in the stirring mixing process), however I never came across any information with regards to static mixing process.
Any thoughts?

Stan,
If you are going to double post, please put a link to the other post in aerospace engineering. This may be the better forum for this question .
For the most part static mixers do not introduce bubbles into the mixture, if the material is already de gassed, a static mixer requires positive pressure to operate so the formation of bubbles is extremely unlikely.
B.E.

You are judged not by what you know, but by what you can do.
