ABSTRACT:
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.
