Small/Medium Sized Cortec VpCI® 126 Vapor Phase Corrosion Inhibitor VpCI Gusset Bags

Daubert Cromwell MetalGuard VCI bags are infused with special Volatile Corrosion Inhibitors (VCIs). When you seal your metal parts inside, these VCI molecules vaporize and create an invisible, protective molecular layer on the surface of the metal. This barrier works by disrupting the electrochemical reactions that cause rust and corrosion, effectively neutralizing the effects of moisture, oxygen, and other corrosive elements in the atmosphere.

These versatile VCI bags are designed to protect a wide range of metals and alloys. You can use them for mild steel, cast iron, stainless steel, galvanized steel, copper, brass, bronze, zinc, and tin parts, making them a really flexible solution for various metal preservation needs.

When properly sealed and stored, Daubert Cromwell MetalGuard VCI bags are engineered to provide long-lasting corrosion protection, typically safeguarding your metal parts for up to 24 months in dry storage conditions. This extended protection offers significant peace of mind for both short and long-term storage or transit.

Absolutely not. One of the great benefits of using these VCI bags is that the protective molecular layer formed on the metal surface is microscopic and invisible. It doesn't alter the metal's properties, so there's no need for any cleaning or degreasing when you're ready to use your parts.

Yes, they certainly are. Daubert Cromwell MetalGuard VCI bags offer a much greener alternative to traditional rust prevention methods like messy oils, greases, or desiccants. By embedding the VCI directly into the bag material, they eliminate the need for additional hazardous chemicals, reducing environmental impact and simplifying disposal.

Daubert Cromwell MetalGuard VCI bags are ideal for a wide array of industrial applications, including protecting manufactured components, machined parts, automotive parts, machinery, and equipment during storage, work-in-progress, and transit. They're often found in manufacturing, automotive, aerospace, and general engineering sectors.

Yes, certain types of Daubert Cromwell VCI films are specifically designed with anti-static additives for the protection of electronic components, making them suitable for this purpose. Always ensure you're using the correct MetalGuard variant if static discharge is a concern.

Definitely. Daubert Cromwell MetalGuard VCI bags are an excellent choice for international shipping, including maritime transport. The VCI formula is effective against common threats encountered during transit, such as salt water, sea air, moisture, and even various gas products, ensuring your metal parts arrive in pristine condition.

The VCI technology in Daubert Cromwell MetalGuard bags is designed to combat the effects of humidity and condensation. The protective VCI layer actively prevents moisture and oxygen from initiating the corrosion process on the metal surface, even in challenging humid conditions.

Yes, many of the Daubert Cromwell MetalGuard VCI formulations are designed for multi-metal protection, meaning they can effectively safeguard a variety of ferrous and non-ferrous metals and alloys simultaneously within the same bag without issue.

For optimal protection, it's crucial to create an airtight seal. You can heat seal the bags using a poly hand sealer, typically for about two seconds at 180°C. For smaller bags, the resealable zip-lock function provides a convenient and secure closure. The goal is to enclose the metal parts completely to allow the VCI vapors to saturate the internal environment.

For the most effective protection, you should place your clean and dry metal parts inside the VCI bag as soon as possible after processing or manufacturing. This minimizes any exposure to corrosive elements before the VCI can begin its protective action.

Yes, they can. While the VCI bags provide primary corrosion protection, they can be used within larger packaging systems, such as cardboard boxes or wooden crates. However, it's important to ensure that the VCI bag itself is securely sealed and that the VCI does not come into direct contact with acidic materials like untreated wood or cardboard, which can absorb the VCI.

To preserve their effectiveness, store unused Daubert Cromwell MetalGuard VCI bags in a cool, dry area, away from direct sunlight. High humidity and temperatures exceeding 80°F (approx. 27°C) should be avoided to prevent premature release of the VCI.

The protective VCI layer has a unique ability to regenerate to a certain extent. While it's best to keep the bag sealed for continuous protection, briefly opening it for inspection typically won't completely compromise its effectiveness, as the VCI vapors will re-saturate the space once resealed.
