Abstract

Abstract INSULATIVE FILM COATINGS FORMED UPON SEPARATED METAL WIRES BY ELECTROPHORETIC DEPOSITION FROM AQUEOUS POLYMER LATEX DISPERSIONS ARE FOUND TO BE CONJOINABLE INTO SUPPORTING STRUCTURES WHICH ARE THICK BY COMPARISON TO DIAMETERS OF ENCLOSED WIRES AND WHICH HAVE PRE-DETERMINABLE DIMENSIONAL PROPERTIES WHEN SOLIDIFIED. ELECTRICAL SIGNAL TRANSMISSION LINES ARE MADE AT REDUCED COST BY THIS PROCESS. WIRES IN SUCH LINES ARE HELD CLOSE TOGETHER WITHOUT TOUCHING AT SPACING DISTANCES HELD TO TIGHT TOLERANCES. THE ELECTROPHORETICALLY APPLIED INSULATING-SUPPORTING STRUC- TURE OF THESE LINES CAN BE PROVIDED WITH SUCH OTHER DESIRABLE FEATURES AS INTERNAL CONTINUITY (I.E. CRACKFREE, VOID-FREE), THERMAL STABILITY, ABRASION RESISTANCE, HIGH DIELECTRIC STRENGTH, FLEXIBILITY, AND UNIFORM COHESION TO THE SUPPORTED WIRES.
