Hi. Is that true the degassing an epoxy resin mixed with anhydride hardener may cause any sort of separation (molecular level???) that will affect the quality of the polymer? This is what I heard but the source is not reliable.

Is there any recommended vacuum pressure for best performance degassing of epoxy resins? What pressure is too much and why? What is minimum pressure?

Compositepro, Thanks for the suggestions. I agree on your statement regarding degradation and moisture absorption, however the amount of the air in the container is driven by the volumetric space of it, because it is sealed. Wouldn't this be exact replication of the normal storage of compound...

I have couple of questions with regards to degassing/storing the epoxy resin (toughened) and hardener (anhydride). 1. Is the any harm to both of the above if I keep them in separated vacuum chambers, isolated and under vacuum pressure instead of original container in the room temperature and...

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...
