Composition and method for corrosion inhibition of metal surface with epoxy resin and an N-tallow-1,3-diaminopropane curing agent
This patent describes a method for treating a metal surface to inhibit corrosion thereof. It comprises contacting the metal surface with a composition comprising an epoxy resin, an N-tallow-1,3-diamino-propane curing agent for the epoxy resin present in an amount such that the equivalent ratio of the curing agent to the epoxy resin is greater than about 1.5:1 to about 5:1, an aromatic hydrocarbon diluent present in at least an amount sufficient to maintain the composition in an essentially fluid state, and an alcohol selected from the group consisting of methanol, ethanol, 1-propanol, 2-propanol, n-butanol, n-pentanol, n-hexanol, n-heptanol and combinations of any two or more thereof, present in an amount of about 10 to about 60 weight percent of the composition to contact the metal surface for a time sufficient to form a corrosion-inhibiting film thereon.
