How is corrosion prevented?
There are many different ways to prevent corrosion, including modifying the atmosphere by dehumidification, nitrogen purge, evacuation, etc., and creating a barrier on the metal surface to prevent the permeation of moisture. This barrier can be formed by a liquid coating, such as oil, or via packaging products that contain VCI or Vapor Corrosion Inhibitors. Vapor Corrosion Inhibitors work by diffusing corrosion inhibiting molecules from a source (packaging film or paper for example) to metal surfaces. These molecules settle on metal surfaces and form a protective corrosion inhibiting layer that inhibits the electro-chemical reactions that cause corrosion to form. NTIC combines the use of vapor corrosion inhibitors with material sciences and process management expertise to implement custom corrosion solutions for a customer or throughout an entire supply chain. We call this our Zerust / Excor® Integrated Corrosion Technologies or “ICT®”.
