The Use of VCI Inhibitors in Conjunction with or Replacement of Traditional Corrosion Inhibitors

The Use of VCI Inhibitors in Conjunction with or Replacement of Traditional Corrosion Inhibitors
Available for download

The use of traditional corrosion inhibitors in paints and coatings continues to be challenged from both an environmental and performance aspect. End users are demanding better corrosion performance, and in many cases, this cannot be achieved with traditional zinc or chromate type inhibitors. The use of VCIs (vapor corrosion inhibitors) in coating formulations has shown that in many systems, they can replace the older technology or significantly improve the performance of the system by working in synergy with the existing inhibitors.

Assuring Quality with Certified Coating Contractors, Applicators, and Inspectors

Those who started in the industrial painting industry back in the 1980s may remember that third-party inspectors, hired by the owner, performed all of the inspection activities and documentation. The NACE Coating Inspection Program (CIP) had just begun in the early 80s, but those getting certified did not work for a contractor. That has changed. Now contractor quality control (QC) and owner quality assurance (QA) are much more clearly defined.

Corrosion Protection in Oil Systems with Water Ingress by Use of Volatile Corrosion Inhibitors (VCI)

Product Number: 51319-12905-SG

Volatile corrosion inhibitors (VCI) are commonly used in various oil systems to prevent corrosion during preservation and in intermittent operation. However water ingress still introduces risk of corrosion when water separates and pools at the bottom of these systems. Traditional corrosion inhibitors used in lubricating oils provide good corrosion protection in the oil-phase but cannot offer protection beneath the oil-water phase line due to their typical hydrophobic nature. It has been determined that the use of proper organic VCIs (which also offer protection in the vapor phase and oil phase) can partition into the water phase and provide additional corrosion protection even in the case of water contamination.
