I am fishing. What kind of effect could helium have on adhesives over long exposures, say 3 years? Question stems from pessure vessel filled with helium for a couple of years, the entire vessel has an insulation material on the outside. The insulation seems to no hold up. The vessel MAWP is about 6psig and is climate controlled. The Vessel is known to leak 5 to 6 x10-7, depending on where you look.
