ABSTRACT OF THE DISCLOSURE Substrates which are susceptible to corrosion by the action of chemical agents in gas-containing and/or gas- generating media are rendered resistant to said corrosion by the application thereto of a coating of a gas-permeable elastomeric or plastic material, and providing for means of escape of gases permeating the coating, thereby maintaining the adhesion of the coating to the substrate. The preferred coating is an RTV silicone elastomer of a particular type as exemplified by "Canadian General Electric RTV 108". Preferably the coating is applied first to a porous backing material such as woven glass cloth, and then t he laminate of coating and porous backing material is adhesively secured to the substrate. The invention has particular application to the lining of electrolytic cells, cell tanks, submerged bus- work, and associated equipment (except electrodes); and also to the lining of chemical process vessels, equipment, piping, valves and the like for use in the production and handling of chemicals.
