  • Method for electrochemically coating a metallic substrate with a protective film of a phenolic resin
    Patent number: 4231851
    Abstract: Adherent insoluble coating film of a phenolic resin is obtained by electrolysis of an alkaline-reacting aqueous electrolyte comprising phenol, a mono- or di-substituted phenol with substituent(s) in o- or m-position, and an alkylene diamine, in specific proportions. The current density shall never exceed 10 mA/sq.cm. The voltage is from 2.5 V to 10 V and is preferably kept constant. Coating thickness values exceeding 1 micron and up to about 25-30 microns are obtainable within a short time at the expense of 2-2.5 Faradays per mole deposited phenol. The substituted phenol is preferably o-chloro-phenol, and the diamine is preferably ethylenediamine.
