Corrosion Prevention Solutions for Sealed Containers and Equipment Storage

VpCI stands for “Vapor phase Corrosion Inhibitors” a breakthrough technology where the corrosion inhibitor substance is transported to metal surfaces through a vapor phase instead of requiring actual contact with metal surfaces (as is typical with traditional VCIs).

Our products are non-toxic and several substrates are completely recyclable; there are no hazardous waste disposal costs.

VpCI products are offered in a variety of formulations, including plastic films, papers, sprays, coatings, high density emitters, bubble and shrink wrap, liquid dips, liquid concentrate (water- and oil-based), grease, migratory power, and gel.

Corrosion inside sealed containers is typically caused by the presence of moisture and oxygen. Even when a container is sealed, trapped humidity or temperature fluctuations can create internal conditions that promote oxidation of metal surfaces over time. Managing internal humidity and environmental conditions helps reduce corrosion risk during storage and transport.

Yes. Sealed containers can still experience internal humidity changes due to trapped air, temperature variation, or pressure-driven air exchange. If moisture levels are not properly controlled, corrosion can develop even without visible external exposure.

Desiccants reduce internal humidity by absorbing moisture from the air inside a sealed container. Vapor corrosion inhibitors (VCIs) release protective molecules that form a temporary barrier on metal surfaces to help inhibit oxidation. Depending on storage conditions and risk factors, one or both approaches may be appropriate.

VCIs are commonly used when metal components require vapor-phase protection during storage or transport, particularly in enclosed environments where direct coatings may not be practical. VCIs may be used alone or in combination with moisture control solutions depending on storage duration and environmental conditions.

The duration of corrosion protection depends on factors such as storage environment, humidity levels, container integrity, and the type and quantity of protective materials used. Long-term storage applications may require engineered solutions based on enclosure size and expected environmental exposure.

Corrosion prevention products are designed to reduce the risk of oxidation by controlling environmental conditions inside a container. While they help mitigate corrosion risk, proper container sealing, handling practices, and storage conditions also play important roles in overall protection.

Selecting an appropriate corrosion prevention approach depends on enclosure size, material type, storage duration, and environmental exposure. AGM can assist in evaluating application requirements and recommending moisture control, vapor corrosion inhibitors, or integrated environmental solutions as appropriate.

Yes. In many applications, corrosion prevention and moisture control are used together to manage both humidity levels and surface protection. Combining approaches may be beneficial in long-term storage or high-humidity environments.
