This article teaches the formulation and use of a screenable adherent polyimide paste with low flow characteristics. In this paste graphite is used as a filler and acts as a sponge to absorb the solvents in which the polyamic acid is dissolved. Thus, the graphite prevents excessive bleedout of the polyimide precursors and undesired flow.
