Process for forming an electrically conductive coating on a nonmetallic filament
Abstract
Abstract A PROCESS FOR FORMING AN ELECTRICALLY CONDUCTIVE COATING ON THE SURFACE OF A NONMETALLIC FILAMENT, CHARACTERIZED IN THAT SAID NONMETALLIC FILAMENT IS CARRIED BY ELECTRICALLY CONDUCTIVE MEMBERS AND PLACED IN AN ELECTRO-DEPOSITING COATING MATERIAL COMPRISING ELECTRICALLY CONDUCTIVE PARTICLES DISPERSED IN A RESINUOUS CARRIER WITH A CONCENTRATION OF 15-25%, PREFERABLY 18-20% BY WEIGHT, SAID CONDUCTIVE MEMBERS WHICH SERVE AS ONE ELECTRODE AND THE OTHER ELECTRODE LOCATED IN SAID ELECTRO-DEPOSITING COATING MATERIAL BEING ELECTRIFIED WITH A D.C. VOLTAGE, THEREBY FORMING A COATING OF A UNIFORM AND DESIRED THICKNESS ON THE SURFACE OF SAID NONMETALLIC FILAMENT. IN THE PROCESS ACCORDING TO THIS INVENTION, AN ELECTRIC CONDUCTOR UMPLOYING A NONMETALLIC FILAMENT AS A CARRIER OR BASE AND HAVING A DESIRED ELECTRIC RESISTANCE CAN BE EASILY AND SURELY OBTAINED BY CONTROLLING THE D.C. VOLTAGE, CURRENT DENSITY OR ELECTRIFYING PERIOD FOR ELECTRO-DEPOSITION, EMPLOYING SIMPLE AND ECONOMICAL ELECTRO-DEPOSITING COATING DEVICES.
