Abstract:
A composition with a corrosion inhibitor component having one or more tetrahydrobenzotriazoles and one or more other triazoles; wherein the tetrahydrobenzotriazoles are in a weight ratio to the other triazoles such that the composition decreases the General Corrosion rate, as measured by copper electrodes in the presence of 10 ppm sodium hypochlorite, by at least about 0.05 mpy relative to a corrosion inhibitor component which is 100% of the other triazoles. Also, a method of using this composition to inhibit corrosion of a metal component which has a metal or metal alloy which is corrodible in the presence of copper or copper corroding agents.
