i.e Urethane is not recommended if the piece is going to be exposed to denaturated alcohol
Butyl is not recommended if it is going to be exposed to fatty acids and so on
Just visited supplier and yes gaskets are post cured for 10 min at 130°C on the autoclave (peroxi)
They told me that the magnitude of influence for the curing to accomplish is the steam pressure
which does not make much sense to me
anyway they just don't want to admit that there was a problem...
Yes failed gaskets were stored somewhere between 1 to 4 months
Some of the stored boxes where slightly collapsed and the carton dividing layers (7 layers per box) where also collapsed

best regards
