  • Composition and method for reducing white rust corrosion in industrial water systems
    Patent number: 8585964
    Abstract: 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.
    Type: Grant

    Date of Patent: November 19, 2013
    Assignee: Nalco Company
    Inventors: Kaveh Sotoudeh, Sherman J. Sprague, Frank Fun-Yuee Lu, Tom Kim
  • Composition and method for controlling copper discharge and erosion of copper alloys in industrial systems
    Patent number: 8470238
    Abstract: Compositions and methods of using such compositions for reducing copper ion discharge from aqueous systems is disclosed and claimed. The composition includes a synergistic combination of at least two different benzotriazoles or salts thereof that effectively provides an erosion-resistant barrier on copper-containing surfaces of industrial systems.
