Wes -- this is a favorite subject of mine and I'm very interested but I have no access to that magazine. Would it be practical for you to copy the article and send it to me? I would really be grateful... Especially if they talk about surface energy at all... Very few writers will address that part of the equation. The way I understand it inherent molecular energy of a surface entering or leaving the water tends to overcome the water molecules' self-attraction. That self attraction underlies the 'film' and its properties. Apparently, materials with greater surface energy have much better 'wetting' characteristics, that is, fluids don't tend to bead-up on them, but readily spread out. This suggests that Gink has low surface energy and Xink has high energy, like most surfactants. But that's just my interpretation and I'm curious if it's true. Hey, maybe our chemists know... Mark and Allan, what's your view? Thanks, Mark __________________________________________________ Do you Yahoo!? Yahoo!
