In an enclosed space, VCI compounds vaporize and bond to the metal, creating a thin coating. This coating prevents the metal from interacting with elements that cause corrosion, like hydrogen and oxygen. Once this protective layer forms, the VCIs release until the package’s interior environment is balanced and stable. VCIs help protect both ferrous and non-ferrous metals from corrosion, rust, etc.

What is a ferrous metal vs. a non-ferrous metal?

Ferrous metals contain iron, and non-ferrous metals do not. Steel is a typical example of a ferrous metal. Common non-ferrous metals usually include base elements like copper, zinc and magnesium.

How long does a VCI product last?

When you store your product correctly in a VCI bag or VCI paper, corrosion protection can last up to two years. The long life span increases your purchase’s value.

What does VCI protect against?

When you wrap or store metals in VCI paper or VCI bags, the materials protect against corrosives like salt, oxygen, dirt and similar contaminants. VCI packaging from Edco delivers the corrosive protection you need.

How long does VCI paper last?

With a two-year shelf life, Edco’s VCI paper is built to last. If you o not use the paper immediately upon purchasing it, you can still expect it to function for an extended period. When storing VCI paper, you need to secure it in a closed or taped box so moisture does not affect its functionality.

Does temperature affect VCI paper?

It is critical to remember that while cold temperatures do not affect VCI paper, extreme heat can reduce the performance of the corrosion inhibitors over time. Correctly sealing the VCI paper’s packaging container helps prevent warm temperatures from affecting your product’s performance.

Do I have to ensure my products are airtight in VCI bags or VCI paper?

We recommend airtight storage to ensure the best possible packaging protection for your metals. Although the packaging’s anti-corrosive properties work better if the metals are enclosed tightly, airtight storage is not always required for the VCI products to work.

Do my parts need to be dry before I store them in VCI bags?

Because moisture is the primary cause of corrosion, keeping your products as dry as possible before and during storage is critical.

Are VCIs environmentally friendly?

Although VCIs are toxic in their natural forms, the coatings and compounds in VCI packaging pose no health risks to workers. Additionally, VCI packaging is recyclable and contains no harmful substances to the environment.
