Frequently Asked Questions What is volatile corrosion inhibition?
• Chemicals used; • Ratios of the chemicals in the formulation; • Compatibility; • Amount of chemical present (coat weight) These factors do not work independent of each other, but are synergistic in making an effective VCI. For example, the best VCI formulation in the world will not be able to provide the 3 to 5 molecule layer barrier on the metal surface if the amount of VCI present in the paper or film is too low (the coatweight). The metal will corrode in spite of the presence of a highly effective VCI formulation. Why does Daubert Cromwell offer so many VCI formulations? Daubert Cromwell’s product line offers different VCI formulations and products to accomplish a broad range of protection requirements. Some companies only offer a “multi-metal” inhibitor. However, to make a multi-metal inhibitor, the formulation must contain a range of corrosion inhibitors some of which are not ferrous inhibitors. Daubert Cromwell does not believe in this “one product fits all” approach. We tailor
