Abstract
A method of printing an electrically conductive thick film ink onto a polymeric substrate. The ink comprises a polymeric binder, which is preferably a fluoropolymer, a solvent for the binder, and an electrically conductive filler. At the printing temperature the solvent is a latent solvent for the binder. After printing the temperature is raised, so that first the binder dissolves in the solvent, and then the solvent vaporizes and the binder cures. The ink may be applied to a conductive polymer, preferably fluoropolymer, substrate and used as a heater.
