Resin/Hardener Air Absorption and Storing under Vacuum
Resin/Hardener Air Absorption and Storing under Vacuum
(OP)
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 atmospheric pressure?
2. If I was to degas both, resin and hardener separately and let the atmospheric pressure into the chamber and keep inside them instead of original container (isolated) is the a chance for the air to go back into each of components if they are not being disturbed/exposed to the moisture and if so after what time approximately?
Regards,
Stan

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

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.e. in the sealed drum? Every time you open drum and take some resin out, then put the lid on you entrap air inside the drum.

You might want to look at Composite pros reply on thread332-355779: Tips to store paint once it is opened! It covers much of the same ground you are asking .
