First of all - roted wood mast be dry before applying penetrating epoxy. It is not possible to dry out wet roted core, period.

With all due respect I think you are confusing "working time/pot life" with "full cure time".
Smith & Co's CPES is the most widely known of the penetrating epoxies. At 68 degrees it has a max pot life of 8 hours! That means it essentially STOPS penetrating at about 8 hours many have shorter pot life time. With epoxies the longer the pot life the longer the full cure. Full cure and workable pot life are totally different.
For a truly dry rotted piece of non-encapsulated wood, like you referenced, CPES works ok. Encapsulated balsa is NOT dry rotted it's wet rotted and CPES or similar products don't work well for THIS application. I've torn it apart many times and seen it's failings and lack of penetration..
