The VCI ions form a shield of protection on the surface of metal that displaces moisture and eradicates rust. VCI Packaging safely prevents corrosion on protected metals without the need for messy grease, oils, protective coatings or other time-consuming methods. How to Prevent Rust in Any Situation In short, the best way to prevent rust is to prevent moisture from reaching the metal, or by using a material that corrodes more slowly.
Use an Alloy: The use of alloys, like stainless steel, is one of the most common ways to prevent rust, or slow it down. Apply Oil: A coating of oil will help to prevent rust or slow it down, since it inhibits moisture from reaching the iron in the metal. However, an oily surface might be problematic for some tools or machines and poses environmental and human health concerns. Apply a Dry Coating: Special rust preventative products dry with no residue and form a protective barrier over metal parts and equipment.
These are effective for products in use, in shipping, storage and more. Paint the Metal: A good quality paint will slow down rusting by preventing moisture from reaching the metal. Store Properly: Store metal parts or products in a low-moisture area, or inside a temperature and humidity-controlled environment to significantly slow down rust. Use of desiccant drying agents in this storage are also helpful. Galvanize: Galvanizing coats iron or steel in zinc to protect from rust. Blueing: This process creates a layer of magnetite over the metal to prevent rust.
The metal must be regularly oiled to maintain rust resistance, and it will turn blue or black in the process. Powder Coating: A layer of acrylic, vinyl, epoxy or other substances will prevent moisture from reaching the metal, thereby preventing rust. VCI Packaging: Vapor Corrosion Inhibitors VCI are a type of chemical compound that when infused into various packaging materials, protect metals by emitting rust eradicating vapors into an enclosed air space to prevent corrosion on a metal surface.
Apply Oil Most gun owners know the importance of keeping firearms well-oiled, even when the weapons are not in use. Applying a dry coat with a product like this can be a useful and versatile way of preventing rust.

Corrosion is the gradual destruction of materials by natural interactions with the environment. Corrosion arises from chemical or electrochemical interactions that are happening all the time. Rust is the most common form of corrosion, happening due to oxidization of metal. Oxidization takes place simply because of direct contact between the affected surface and oxygen molecules.
To maintain the performance of industrial materials, a plan to prevent corrosion is essential. Equipment and surfaces can be defended from some corrosion by maintaining appropriate work conditions — for example, reducing humidity and preventing incidental spillage of corrosive agents.
However, industrial coatings are the most effective and longest lasting approach. Whether you need to protect a piece of equipment, a pipe, a wall, or flooring, the right industrial coating is essential. Coatings provide chemical protection against corrosion on a molecular scale.
Rusting takes place when oxygen in the environment bonds with iron or an alloy that contains iron. Iron forfeits electrons to the oxygen, facilitating oxidization. The rusted surface is much weaker than it was initially and may not stand up to design tolerances. One of the most common approaches to corrosion prevention is the application of a sacrificial coating. A more reactive metal with a lower rate of corrosion is used to protect the base surface from rust. This is seen in galvanization, where a thin layer of zinc is applied to steel or iron.
The resulting alloy has a far longer service life than unprotected metal. Not only is this a common and affordable procedure, it helps control costs associated with replacement. Paints for industrial applications provide some protection but are not usually sufficient alone.
To maximize performance, the right industrial coating must be matched with the right job. Antirust coatings can be applied directly onto a fully-painted surface. The exact type of coating and how it works depends on the underlying metal. These mimic the properties of galvanized steel by providing a new sacrificial layer.
This can be applied in addition to or instead of new coats of paint. This compound converts existing iron oxide into a chemical barrier that protects the substrate. Most rust converters are water-based and use an organic polymer for the protective effect. Any treated rust will change from red to black. Rust can cause inconsistent equipment performance and lead to equipment failure. It may cost only a few hundred dollars to proactively guard against rust — compared to thousands for a new piece of equipment that may take weeks to arrive.
