Hi Corby, I figured that you had a good reason, but from casual viewing of the pictures you provided the coating looked pretty reasonable, so I wondered.
The stabilizing agents are the key. Teflon particles don't like water sticking to them all that well, hence their use in things like gortex. The stabilizing agents are probably just a surfactant. I think I might try an experiment with some of the teflon spray lube relative to outgassing... If I can find a few spare hours. I would suggest, that unless you are well experienced in handling such coatings, you try it out on something easier to evaluate, like perhaps a flask. -Chuck Harris cdel...@juno.com wrote:
Chuck, The coating opposite the entrance to the bulb was degraded to the point that it was missing over a large area and the tiny particles of loose Teflon were free to move about in the bulb. (Rolling the bulb you could see a little pile of particles moving about) Since a majority of the hydrogen atoms entering the bulb impact first at the opposite end that would cause a large majority of the atoms in the correct state to be perturbed as well as recombine into molecules. So since the end needed recoating it's best to do the whole thing. Per the question of aqueous dispersions here is an excerpt from Dupont: DuPont™ Teflon® aqueous dispersions are milky white dispersions of PTFE particles in water, stabilized by wetting agents.
