VCI Paper: Rust Prevention Doesn’t Have to Be a Dirty Job

Protecting metal parts from corrosion while in production, in storage or in shipment is a challenge. Corrosion’s damaging effects can strike at any point in the manufacturing process:

• Newly machined parts are highly susceptible to flash rust or corrosion because the metal’s surface is fresh and unprotected;
• Metal parts in storage may be exposed to moisture, salt, airborne chemicals or contaminates; and
• Metal parts in shipment or transport are likely to experience fluctuations in temperature and humidity.

To keep your metal parts corrosion-free every step of the way, wrap them in protection and wrap out rust with an anti-rust paper like VCI WRAP. Made from Kraft paper that has been infused with Vapor Corrosion Inhibitors (sometimes referred to as Volatile Corrosion Inhibitors), this rust prevention paper is specifically designed to protect metal parts from corrosion while in process, in storage or in transport.

How VCI Paper Prevents Rust

VCI is a class of chemical compounds that emit corrosion-inhibiting molecules into an enclosed air space. When VCI is combined with Kraft paper, the result is a anti-rust paper packaging material that prevents rust.

When metal parts are wrapped or enclosed in VCI paper, the VCI vapors are released and they attach to the surface of metal to form an undetectable shield of protection that keeps dirt, water, moisture and corrosion-causing contaminants away from metal.

Traditional rust preventatives — such as oil or grease – protect metal with a physical barrier that is messy and labor intensive to apply. VCI, on the other hand, protects metal with a molecular barrier that is non-detectable and does not change the look, weight or feel of metal parts, and it does not compromise metal surface coatings or treatments.

Better yet, once metal parts are removed from VCI paper, the VCI dissipates leaving metal parts ready for immediate use. The added work of cleaning or degreasing that is required from rust preventative oils and greases is eliminated!

VCI Anti-Corrosion Paper Makes Rust Prevention Easy

VCI anti-corrosion paper is designed to keep both ferrous and non-ferrous metals rust free, and thanks to the inherent flexibility of paper, it is ultra-easy to apply and ideal for most sizes and shapes of metal parts. To use, simply wrap metal parts or interleave VCI paper between layers of metal parts in storage containers or shipping crates.

Some VCI papers, such as ARMOR WRAP®, are not only manufactured in a variety of sizes of cut sheets or rolls, but they are also available in different formulations such as global, multi-metal and military-approved. Many also offer the option to add a coating to the VCI paper such as a wax or poly to increase protection against moisture, grease or oils, or scrim for added durability and tear resistance.

The Benefits of VCI Paper

Rust prevention does not have to be a “dirty job.” Use VCI paper to eliminate the time, labor and mess of applying and removing rust preventative oil or grease. In addition, VCI paper sheets or rolls simplify the application process while keeping it clean, dry and effective. Work smarter, not harder with VCI paper and its many benefits:

• CLEAN: no messy oils or grease to apply or remove
• SAFE: VCI paper is environmentally friendly, recyclable and re-pulpable
• EASY-TO-USE: flexible packaging material; easily forms around differing shapes and sizes of metal parts
• WORKS FAST: paper releases VCI quickly, which allows VCI to form its protective shield on the surface of metal parts fast
• EFFECTIVE: protects metal from corrosion for up to 3 years

How to Prevent Rust Without Paint, Oil or Grease: Try VCI for Dry Rust Prevention That Works

Rust has plagued manufacturers, distributors, engineers and fabricators for hundreds of years. This pesky substance breaks down all types of iron-based metals, and often seems impossible to prevent. Rust-preventing paints, oils or greases are common methods used to keep metals from rusting, but they’re not the only methods. Let’s take a look at how to prevent rust without the mess and hassle of paint, oil or grease, using a dry rust prevention method called VCI instead.

How to Prevent Rust Without Paint, Oil or Grease: Try VCI for Dry Rust Prevention That Works

Corrosion and rusting are two chemical processes that result in the breakdown and disintegration of materials, the most common of which is metal. Both are the result of a metal’s exposure to factors such as water, moisture and air. Corrosion is a term that references the gradual degradation of metal due to a chemical reaction with its environment. While rusting, on the other hand, is defined as a specific type of corrosion – one that occurs with iron-based (or sometimes referred to as ferrous) metals. More important than the semantics of these terms is the damage to metal and metal parts that they can leave behind.

But all is not lost, there are effective ways to keep metal and metal parts rust free. One way to prevent rust on ferrous metals is to cover the surface with a coating such as paint, oil or grease, to prevent moisture and air from making direct contact with the metal. However, coating metal parts is “messy business” – it is labor intensive and time-consuming to apply and to remove, and it isn’t always a feasible way to prevent rust. Sometimes items just can’t be painted. The good news? There is another way to prevent rust. The even better news? It is a clean, safe, easy-to-apply and dry rust preventative – what more could you ask for? The method behind it is VCI, or Vapor Corrosion Inhibitor.

Vapor Corrosion Inhibitor

Vapor Corrosion Inhibitors (sometimes referred to as Volatile Corrosion Inhibitors) or VCI for short, top the list as one of the best dry rust prevention methods. VCI is a class of chemical compounds that emit rust-inhibiting vapors into an enclosed air space. VCI is combined with resources like Kraft paper or polyethylene film to create packaging materials with the added benefit of rust prevention such as VCI WRAP or VCI POLY film.

How does VCI Work?

VCI protects metal in ways that paint, oil and grease can’t – instead of providing a physical barrier, VCI works on a molecular level to prevent rust. To protect metal parts, simply wrap or enclose them in VCI paper or film. VCI vapors will be released from the packaging material and they will form a clean, dry, ultra-thin and ultra-strong layer of protection on the surface of metal that is only a few molecules thick. This VCI shield of protection keeps dirt, water, moisture and corrosion-causing contaminants away from metal.

When VCI is used properly, it provides reliable, high-quality protection against rust without the need for messy paints, oils or grease. In addition, VCI is nearly undetectable; it does not change the look, weight or feel of metal parts; it does not compromise metal surface coatings or treatments; and it leaves metal parts ready for immediate use without cleaning or degreasing.

It is hard to ignore the benefits of dry rust prevention using VCI paper or poly film. It is cost effective; easy to apply; eliminates the mess and labor of paint, oil or grease that is required to apply; does not require removal; and it can provide years of protection. Wash your hands of the mess and work of using paint, oil or grease to prevent rust, VCI rust-prevention products are the clean, safe and dry alternative.

ARMOR SEA FILM™: Extreme Protection for Extreme Conditions


If you manufacture metal parts that will be exposed to the elements during outdoor storage or overseas transport, rust and corrosion are a very real threat.  ARMOR VCI SEA Film™ is formulated to withstand Mother Nature’s most threatening outdoor conditions while protecting metal and metal parts from the damaging effects of rust and corrosion that could form as a result.

If you’re wondering how SEA Film is able to keep metal parts rust-free in extreme conditions when other VCI films can’t, we’ll let you in on the secret – three-layer construction.  We combine the strongest characteristics of three different films to manufacture this holy grail of rust-preventing VCI film and we aren’t shy about touting that ARMOR SEA Film is even more amazing when you consider that it gives high performance without high cost.



OUTSIDE LAYER:  manufactured in white exterior to reflect sunlight and contains an Ultra Violet (UV) light inhibitor to stabilize film from breaking down due to extended UV exposure and its damaging heat.

CENTER LAYER:  provides a heavy-duty physical barrier that protects metal/metal parts from moisture, contaminates and the harshest of outdoor conditions.

INSIDE LAYER:  strategically places ARMOR’s rust-preventing VCI Nanotechnology™ (a.k.a., our “secret recipe” for vapor corrosion inhibitor) closest to metal/metal parts to maximize protection.

The value of SEA Film’s unique multi-layer construction extends beyond its effectiveness in preventing rust, it offers opportunity for cost savings as well. Not only does SEA Film provide an ultra-strong physical barrier, it’s engineered to keep ARMOR’s rust-preventing VCI Nanotechnology™ (a.k.a., our “secret recipe” for vapor corrosion inhibitor) in the inner layer.  Positioning VCI close to metal parts, where it is needed most, often means that the film can be down-gauged to reduce cost without compromising performance.
