How To Enhance Rust Protection using VCI and CCI Combined Technologies?

There are many temporary corrosion prevention techniques available in the market today. Yet it has been realized that when a combination of VCI and CCI technologies is used, the result is even better.

Understanding VCI and CCI Technologies

VCI is the technology that makes use of the volatile corrosion inhibiting molecules within the wrapping products like paper sheets, poly films, and so on. These molecules come into play when the wrapping material comes near to the metal product. The polarity of the VCI molecule ensures that the VCI from the wrapping material are attracted and settled on the metal surface and form a layer of 3-5 molecule. This seals off the metal surface and forms a barrier against any corrosion-causing contaminants.

CCI technology on the other hand makes use of the contact corrosion inhibition concept. Products like rust preventive oils, coatings or waxes are based on CCI technology. In this, the rust preventive oils are coated onto the metal surface of the object to protect the parts or component from corrosion.

In both cases, these technologies are best utilized in manufacturing, storing, and transportation purposes of metal objects from the automobile and engineering industries.

Corrosion Protection Performance after Combining these Technologies

Either of these technologies VCI or CCI would be enough to protect any metal product from corrosion. But the use of the two together is a great combination with remarkable corrosion protection capability. This is best in the case where the environment and atmosphere are moist and condensed, like sea shipment or high rain areas. This combination leads to the following conclusions:

 

1. The protection life of the preserved metal objects is extended.

2. Cost and technical objectives are met by the optimized use of both technologies in tandem.

3. The limitations of individual technologies are countered by the combination.

 

The overall performance of corrosion protection after combining the technologies is visible from the above-mentioned conclusions. The compatibility of the rust preventive oils, and the volatile corrosion inhibitor products play an important role in corrosion prevention performance. The understanding of their chemistry is vital to ensure no negative points come into the highlight during their association.

 

They work together to extend the life of metal objects. Rust preventive oils have a naturally exhaustive life. Over time, the natural barrier is broken by the repeated pressure from the natural atmospheric cycles. On such an occasion, VCI molecules come into play. This, therefore, extends the life of the metal component till the VCI layer reaches its end.

Use of Optimized Quantities of both to Achieve Technical Objectives

Export of metal parts and objects across seas areas might require longer commute duration. For the same, the corrosion protection must be extended by several months. At the same time, the use of rust prevention methods should always result in the best solutions that are light and non-interfering with the transport process while meeting cleanliness standards.

 

For this thicker layering of best-quality rust preventive oils on a standalone basis was utilized earlier. This required the extra cost of cleaning and the additional cost of thicker layering of the oils. To balance the expenses, the use of Daubert VCI materials along with rust preventive oil such as NOX-RUST both in optimized quantities can help meet the cost and technical objectives.

The Combination Covers the Limitations of both Technologies

When VCI materials are required for utilization, there are some strict pre-application guidelines and a must-be-followed to-do list. This includes cleaning the surface thoroughly to ensure no dust, dirt, moisture, fingerprints, or any residues are remaining. This level of thoroughness is not possible in manufacturing units that follow conventional processes and have been long-standing in the industry. Hence, such manufacturers can utilize Rust preventive oils as the first layer of coating as these are light and do not require much hassle expect for cleaning off moisture.

 

Additionally, these rust preventive oil coatings are protected further by the VCI materials. Conversely, the order of using the corrosion protection materials can change as the corrosion protection oil is lightweight and capable of being used anyhow.

 

Therefore, the use of the VCI and CCI technologies together in certain combinations has proved to be economical and more beneficial in applications. The best results can be seen during export procedures of metal parts and objects.
