When considering corrosion protection methods, plenty of options are available. For protecting metals during the manufacturing processes of shipment and storage, the two methods most used are corrosion inhibitor liquids and VCI (volatile corrosion inhibitor) packaging products. Corrosion inhibitor liquids, also known as “Rust Preventatives” (RPs) or oils, are available in a wide range of
When you mention the words “rust season” to someone in the metalworking industry, you may get a dry smile. Their immediate answer is typically summer, when high heat and humidity create the perfect conditions for corrosion. That answer is usually quickly followed by reasons why the rest of the year their metals can also corrode.
April was Earth month but did you know during April, Corrosion Awareness Day also occurred? While this date isn’t as well-known, preventing corrosion is an important way to help the environment and conserve natural resources. Whether you are a civil engineer overseeing infrastructure, a quality-control manager at a metalworking facility or have a nice set
Often people interchange the product names VCI Shrink Film and VCI Stretch Wrap, but they are two distinct packaging films. They are both Volatile Corrosion Inhibitor (VCI) protection infused films, but their mechanical properties are different. VCI stretch film VCI stretch film is used to tightly bundle items such as pallets. It is like cling wrap and
When shipping metal parts in cardboard corrugated boxes, do you allow the unprotected parts to touch the box? If so, then the corrugated may be the source of the corrosion. When cardboard boxes are manufactured, the paper begins as a pulp and is then dissolved using nitric acid. In order to neutralize the acid before
Volatile Corrosion Inhibitor (VCI) Packaging is an effective way to prevent corrosion on metals. When packed correctly, VCI packaging can protect clean metals for years in shipping and storage. Typical VCI packaging products are VCI poly sheeting, VCI bags, VCI Kraft paper, and other VCI wraps. These packaging products are used to line containers or create
Volatile Corrosion Inhibitors (VCIs) have been around since the 1940’s, when a product named Dichan was introduced into market. Dichan consisted of dicyclohexylamine-nitrite, which was described as a vapor phase corrosion inhibitor that had sufficient vapor pressure to release corrosion inhibiting molecules into the surrounding area. Eventually, this chemistry began to be coated onto paper,
Often people confuse VCI (Vapor or Volatile Corrosion Inhibitor) with desiccants, as they both are used to control corrosion during shipping and storage. However, the way these chemistries work is much different. Depending on the application, environment and length of protection, you may get better results with VCI vs desiccants. Some highly effective packaging systems
