Dear David,

We do not have methane - epoxy resins, but we have some permeability figures for nitrogen - epoxy.

Nitrogen at 25 degrees Celsius and 1 bar:

Thermoplastic Epoxy:
1.8 E-14 [m3 stp / m3 x bar] x [m2/s]
(Dow Plastics Blox High Adhesion Barrier Resins)

Bisphenol-A Epoxy Resin (Rigd Epoxy):
1.5 E-13 [m3 stp / m3 x bar] x [m2/s]

Please contact us for more information. If you got additional permeability figures of gases (mixtures) for all types of epoxy resins, we invite you to contact us.

Kind Regards,
