  • Patent number: 9539456
    Abstract: The present invention includes formulations and methods to reduce Cr(VI) contamination, in which the formulation comprises (1) a reactive reducing agent comprising at least one reducing chemical capable of reducing Cr(VI) to Cr(III); and (b) one or more solvents. Moreover, the present invention includes formulations to reduce Cr(VI) within the coating, and Cr(VI) reducing kits with at least one color reference tool for evaluating the process and/or completion of the Cr(VI) reduction.
    Type: Grant

  • Patent number: 8722147
    Abstract: A corrosion resistant primer coating comprises one or more corrosion inhibiting additives; and one or more nonaqueous resins, and the method of making and using the primer coating. The corrosion inhibiting additive comprises metal ferrate(IV) compounds, metal ferrate(V) compounds, metal ferrate(VI) compounds, or a mixture thereof (collectively called the ferrate compound). The ferrate compound has a low solubility in water in the range of about 0.001 ppm to about 2000 ppm at a temperature in the range of about 0° C. to 71° C.

  • Patent number: 5446369
    Abstract: The corrosion monitor system facilitates the detection and monitoring of material corrosion in remote areas. Sensors, which react to a corrosive environment similar to the material to be monitored, are placed in isolated areas and connected to a central control system via shielded cables. The system consists of a controller board, multiple dual preamp boards, a battery pack, sensors, and corresponding cables. The controller board consists of a microcontroller, memory, data conversion, and other control circuits. The dual preamp boards contain multiple precision instrumentation amplifiers, filtering, and voltage conversion circuits. The system operates on the principal that corrosion of a metallic conductor will cause a corresponding increase in the cross-sectional electrical resistance of that conductor. This change in resistance can be detected and monitored by passing a known constant current through the conductor and comparing the voltage across the conductor with that of a controlled reference conductor.
