Increase in GFM in time

Hi to all!

I read on Jacobs' "Stereolithography and other RP&M Tecnologies" that an
epoxy resin like SL 5170 and SL 5180 increase their GFM (green flexural
modulus) for more than 25 hours after building.
Can anyone tell me when this increase stops (I think it should stop,
because this is due to completion of photopolimerization)?
Anyone has had the need of measuring GFM and use this measure some time
later?

thank you all
