ARMOR engineered highly-specialized vapor corrosion inhibitors to create its unique VCI formulation called ARMOR VCI Nanotechnology. This “secret recipe” of VCI forms a rust-resistant protective shield on the surface of metal that is only a few molecules thick called a “nanocoating.”
With competitive price and timely delivery, Yuanlong Packaging sincerely hope to be your supplier and partner.
Nanotechnology is described as the imaging, measuring, modeling and manipulation of matter in extremely small sizes of between 1 and 100 nanometers. To illustrate just how small a nanometer is, consider these examples:
ARMOR VCI Nanotechnology protects metal in ways that traditional oil and grease rust prevention methods can’t – it delivers a clean, dry ultra-thin and ultra-strong layer of protection on the surface of metal that is only 4-to-6 nanometers thick. The VCI molecules form a hydrophobic (aka, water-repelling) barrier that keeps dirt, water, moisture and other corrosion-causing contaminates away from metal. ARMOR’s VCI formulation forms a layer of protection that is undetectable and that does not alter metal properties — 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.
When you wrap or enclose a metal part in an ARMOR VCI product, VCI vapors are released and they attach themselves to the surface of metal to form a nano-sized layer of protection that repels water, moisture and other contaminates that cause corrosion. Traditional rust preventatives such as oil and grease offer a physical barrier to protect the surface of metal parts, but they are messy, time consuming to apply and remove, and are harmful to humans and the environment. Vapor corrosion inhibitors (VCI), such as ARMOR VCI Nanotechnology, work on a molecular level and they are clean, dry, easy-to-apply, and VCI protection dissipates once metal part is removed from VCI packaging, which eliminates the need for removal.
Nitrites are used in VCI in the form of sodium nitrite. Sodium nitrite has been used as a food preservative for over 100 years. It is found in the bacon you eat for breakfast and the salami you eat for lunch. It has been approved as a food additive for over two-thirds of a century. In fact, over 85% of the sodium nitrite present in our body is produced by our own body. In order to consume the MSDS reported hazardous dosage of sodium nitrite, for a normal VCI at 1.0 g/sq. ft. a person would have to EAT all of the sodium nitrite present in 31 sq. ft. of VCI treated paper. Not only does a person not ingest VCI paper, but rarely comes into contact with it, given the fact that workers should wear gloves to avoid the acidity that our fingerprints give off on the metal surfaces.
Similar to most ordinary household chemicals, sodium nitrite is not without risk. It simply must be handled in the same judicious fashion as such ordinary chemicals as household bleach, windshield washer fluid, floor wax, and several others. None of these components would be considered as “hazardous” within normal usage; however, sodium nitrite is often singled out as if it is. While sodium nitrite in VCI Paper should not be construed in the same light as a food preservative, it is not the lethal enemy that some make it out to be. It is used in the VCI industry because it is an excellent inhibitor of rust, especially for steel products. Armor Protective Packaging® manufactures several different VCI products, with and without sodium nitrite. Please contact an ARMOR representative for information and help in specifying the correct product(s) for your application.
From strictly a corrosion inhibitor standpoint, paper has been a better inhibitor of rust due to the way that the VCI is impregnated into the paper, and is released into the air and onto the product. VCI papers have been in existence for over 50 years, first adopted by the United States Military. VCI because of paper characteristics is able to protect a part quicker coming off of a paper, than it is off of polyethylene. This is not to say that VCI poly is not an excellent product or that it does not have its place. However, from a pure rust inhibitor issue, paper has proven over the long haul to be slightly more effective.

VCI and desiccants protect metal parts in very different ways using very different chemistry. One way to explain their differences is using a give-and-take analogy. ARMOR’s proprietary VCI Nanotechnology “gives” or emits a vapor that prevents corrosion by forming a protective layer on the surface of metal. Desiccants are drying agents that “take” or adsorb moisture from the packaging environment, which is one of the main causes of corrosion. Depending on the application and the particulars of the storage or shipping environment, one method may provide better results than the other or, VCI and desiccants are often used together to provide premium protection of metal parts in highly-demanding packaging environments.
In , ARMOR formally combined VCI and desiccant together to create its SMARTY PAK™. The SMARTY PAK design not only emits ARMOR VCI Nanotechnology, it uses a specialty desiccant that adsorbs moisture faster than traditional desiccants and holds on to the moisture even at high temperatures. SMARTY PAKs are available in three sizes, they deliver multi-metal protection, and they are non-dusting and lint-free making them ideal for use in applications where fibrous packaging materials are not allowed.
Corrugated cardboard is made from paper. An early step in the method for making paper involves treating raw wood with chemicals to break it down into a fibrous pulp – it is an acidic process and it can leave an acidic residue on cardboard. One characteristic of corrugated cardboard is it is absorbent and when it absorbs water/moisture it causes the acidic residue to activate. If metal or metal parts in storage or transit are placed directly on or near damp corrugated cardboard, the moisture and acidity will induce corrosion on the surface of metal parts. Placing ARMOR VCI products between metal and corrugated cardboard will prevent corrosion and keep metals clean and rust-free.
In our more than 40 years in business, ARMOR has never been contacted regarding an issue with VCI compatibility to non-metallic surfaces such as plastics, rubbers or wood. However, since there are so many possible combinations of ingredients, processes and types of these substrates it is impossible to guarantee their suitability with ARMOR VCI. Without question, rust prevention methods such as oils, greases and other liquid RPs (rust preventatives) have a much higher likelihood of reacting with plastics, rubbers and wood, but ARMOR strongly recommends a check of VCI compatibility with these substances for each application due to the complexity and number of plastics, rubber materials and woods in the marketplace.
ARMOR can tell you exactly how much VCI is contained in our products to give your products the added insurance they need to remain corrosion free. For example, our papers contain a specified and measured amount of VCI additive, as measured in grams/square foot. This ability to monitor and control the amount is a testament to our quality and continued improvement. If a company cannot specify and consistently meet a given coating weight of VCI on a substrate, one runs the risk of having too little VCI to get the job done.
Oil, lubricants, and/or transmission fluids typically do not have any adverse effects when used in combination with VCI other than they inhibit the full potential of the VCI. ARMOR VCI was developed to be used on parts that are clean and dry (free of RPs and oils). If parts are coated with these types of liquids, the VCI may not be able to penetrate through the coatings to get to the metal surfaces. ARMOR VCI, will however, protect recessed areas or other areas where the oil/lubricant/transmission fluid is not, thereby guarding against corrosion in that regard. ARMOR recommends lab testing if there is concern regarding compatibility.
