ABSTRACT:
Trichlorotrifluoromethane is used as a vehicle to apply carbon and a binder to a substrate. Carbon black and tetrafluoroethylene are suspended in liquid trichlorotrifluoroethane to form a slurry. A layer of the slurry is deposited on a substrate. The trichlorofluoromethane is evaporated leaving a porous residue of carbon and tetrafluoroethylene on the substrate.
