Does VCI Desiccant Need to Be in Contact with Metal to Be Effective?

In the imagination of many people, to protect the metal from rust, the rust inhibitor must be applied directly to the metal surface. Then volatile corrosion inhibitor, do you need to stick to the metal parts tightly when using it?

 

Gas phase action: protection without contact

The anti-rust core of volatile corrosion inhibitor lies in the gas phase. The volatile corrosion inhibitors contained in it will continue to evaporate automatically at room temperature and become gas molecules. These invisible anti-rust molecules will quickly spread into the entire airtight packaging space. They can actively find every metal product, whether it is a smooth surface or a complex thread or groove, and they are firmly adsorbed on it to form a protective film. This film can effectively block moisture and corrosive gases in the air from contacting the metal surface and prevent corrosion. Because of this protection, volatile corrosion inhibitor does not need to be in direct contact with metal. You only need to place it in the right place in the box, and it can provide uniform and comprehensive protection for metal products in the entire space.

 

Double protection: the combination of anti-rust and moisture absorption

Our volatile corrosion inhibitor is a dual protection product. It can quickly release corrosion inhibitor molecules and establish a stable gas phase protective layer around the metal. Even under harsh storage or shipping conditions, the metal can remain as bright as new. It also has a strong hygroscopic activity, which can actively absorb environmental moisture in the packaging space and reduce the relative humidity in the packaging. It is especially suitable for ocean transportation or metal products stored in a high humidity environment.

Safe packaging: sturdy and environmentally friendly

Our VCI products use DuPont paper and high-grade non-woven fabrics for double-layer packaging. This design ensures that the internal anti-rust powder will not leak, is tough and durable, not easily damaged, and guarantees the integrity of the transportation and handling process. And the material composition of all our volatile corrosion inhibitors is strictly controllable, non-toxic and harmless. Our products comply with the internationally renowned ROHS and REACH regulations, and are a green and environmentally friendly anti-rust product. You can safely use it for the packaging of export products and precision instruments without worrying about any safety or compliance risks.

 

Our production capacity and commitment:

CVCI has a mature production process and a strict quality control system. Our production line can ensure the stability of the corrosion inhibitor composition in volatile corrosion inhibitor, and ensure that each package of products that leave the factory has consistent anti-rust and moisture absorption properties. We know that the needs of different customers are different, so we have flexible production capacity and can provide volatile corrosion inhibitor of various specifications and sizes to meet the different packaging needs from small precision parts to large machinery and equipment.

 

Choosing our VCI product does not require you to laboriously apply or place it tightly. It only needs to be placed in the package to create a dry and rust-free environment for your metal products to be well preserved. If you are interested in our products, please feel free to contact us!
