PRODUCTION OF THIN POLYTETRAFLUOROETHYLENE RESIN (TEFLON) COATINGS BY ELECTRODEPOSITION METHODS

Abstract

An electrodeposition method of applying thin polypolytetrafluoroethylene resin (''Teflon'') coatings has been develop which allows the application of crack-free films up to 0.001 in. thick in one coating operation. Polytetrafluoroethylene (TFE) coatings applied by this method are intended to supplement sprayed TFE coatings in lubricating, without the use of oils or greases, a wide variety of military equipment. Electro deposited TFE coatings possess a very low coefficient of friction on steel, are smooth and free from blisters, cracks, coagulated particles and other surface defects and exhibit adhesion (under simulated dry lubricant conditions) comparable to sprayed TFE coatings. Electrode posited TFE coatings are plated from a bath com posed of TFE (Teflon 41BX), perfluorooctanic acid (stabilizer), pigment and fluorinated ethylene propylene (FEP) or alumina modified colloidal silica as adhesion aids. Extending the sintering time over that normally employed, aids in im proving the adhesion of the electrodeposits to steel substrates.
