ZERUST®/EXCOR® (Vapor or Volatile Corrosion Inhibitor) VCI film, poly bags, and tubing are produced using a process known as blown film extrusion. The polyethylene is melted and extruded into sheeting which is then slit, folded, or sealed to the desired size and dimensions. With ZERUST’s vast manufacturing network, we have over 100 extrusion lines in

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 pulp and is then dissolved using nitric acid.  In order to neutralize the acid before

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,

When it comes to corrosion prevention during shipping and storage, two common methods are often discussed: Vapor Corrosion Inhibitors (VCIs) and desiccants. Although both aim to protect metal surfaces, their mechanisms and ideal applications differ significantly. Understanding these differences can help you choose the most effective solution based on your specific needs, environment, and duration
