Storage time of basified A/B mix in HDPE plastic

[Rolande]

Hello Nexians!

Someone who I know was wondering how long he can store his basified mix in HDPE containers without any contamination?

Thank you for sharing knowledge,which thankfully is still legal!

i think indefinitely in as far as base goes.

it is the choice of solvent where contamination becomes a concern.

though i BELIEVE (someone please correct me if i am wrong) that hdpe is safe with aliphatics, and only a concern (and not a definitive one at that) with aromatics.
