Abstract
A method is provided for producing a corrosion resistant metallic article. The article to be protected is coated with a solution containing a polymeric composition drawn from the class of polymers commonly known as polybenzimidazoles, followed by drying or curing of the coated article. The coated metallic article resists corrosion under severe conditions. The coating adheres well, being non-peeling and resistant to organic solvents and heat.
