|Helium and water vapor diffusion coefficient in epoxy|
Posted by Jian Sun on January 09, 2007 at 19:08:08:
To whom will concern it:
I am looking for diffusion coefficient values for Helium gas and water vapor in epoxy resin and epoxy composite building materials at room temp (25c). Also I notice that the unit for permeability in volume is m2/s, how shall I calculate the total volume per second with given thickness and area of epoxy?
