Kelly, Thanks for your response. What we're trying to achieve here is an EMI shield at the ends of a flex circuit. Imagine an outline that resembles a ginger bread man (no kidding). I'm trying one option of using a flexible conductive type epoxy to achieve total shielding between the layer edges and in between the flex layer themselves. I realise that what I'm asking for may not be attainable with the parameters outlined, NASA approved little or no outgassing, no particulates and able to withstand a sustained space environment. Any ideas??
