COMPOSITION AND METHOD FOR REDUCING WHITE RUST CORROSION IN INDUSTRIAL WATER SYSTEMS

摘要

This invention provides a novel, synergistic composition and method for reducing corrosion, particularly white rust corrosion, on galvanized metal surfaces in industrial water systems. The composition is a synergistic blend and preferably comprises from about 0 to about 10 weight percent of an amine-based white rust corrosion reducer and from about 10 to about 90 weight percent of a benzotriazole. In a method for using the synergistic blend, an effective amount of the blend is introduced onto the galvanized metal surface to form a barrier on the surface. After one or more time intervals, the composition is optionally overlayed onto the initial barrier by reintroducing an effective amount of the composition onto the galvanized metal surface
