<p>PURPOSE:To obtain an electrically conductive printing paste capable of keeping stable electrical conductivity and electrical contact over a long period by mixing a specific fine powder of a fluororesin to an electrically conductive printing paste containing a resin binder, electrically conductive powder and a solvent. CONSTITUTION:The objective paste can be produced by mixing (A) an electrically conductive printing paste composed mainly of a mixture of (i) a resin binder, (ii) electrically conductive powder and (m) a solvent with (B) 2-30 pts.wt. (based on the solid component of the component i) of a powdery fluororesin (e.g. polytetrafluoroethylene resin) having an average molecular weight of <=10,000, particle diameter of <=10mum and kinetic frictional coefficient of <=0.5.</p> |
