Hello!

I am looking for permeability-, solubility- and
diffusion-constants for hydrogen in the following materials:

- EpoTek 302-3M (an epoxy resin from Epoxy Technology)
- Silicone fluids (as for instance Dow Corning 200/20 cst)

If possible at different pressures and operating temperatures. Could you provide any data on the hydrogen permeability-, solubility- and/or diffusion-constant for these materials and? What about the chemical and mechanical properties, dimensional change of these materials

Regards,
Steven Ellison
