an electrically conductive composition useful , for example , in screen printing applications , includes a thermoplastic resin binder , electrically conductive particles and a solvent . the preferred composition includes a polysulfone thermoplastic resin , silver flakes or carbon black as the conductive particles and butyrophenone as the solvent . the preferred manufacturing process includes adding the resin in two batches at separate time periods during the mixing of the components . the composition is particularly suitable for fusion at high temperatures , such as in screen printed electrical contacts for use in capacitance humidity sensors .
