<p>Polymer thick film inks which comprise a polymeric binder, a conductive filler, and a latent solvent for the binder, i.e. a solvent which does not dissolve the binder at printing temperatures but does dissolve the binder at elevated temperatures. At the time of printing, the binder is present in the form of particles dispersed in the solvent. The printed ink is then heated first to dissolve the binder and then to cure the ink. Preferred inks contain a fluropolymer as binder, in particular polyvinylidene fluoride.</p> |
