The use of anti-corrosive packaging materials functionalized with volatile corrosion inhibitors (VCI) to preserve processed metal parts is critical for any good corrosion management program. Evaluating the efficacy of VCI packaging to provide off-contact protection of steel surfaces is commonly performed in the laboratory using the Vapor-phase Inhibition Ability (VIA) test, also known as the

While the NACE Standard TM0208 Vapor Inhibition Ability (VIA) test, also known as the VCI jar test, is a powerful tool for rapid analysis of VCI packaging and chemistry, it isn’t always robust enough to evaluate the complete protection of VCI packaging. In addition, it is even more limited in its capabilities for testing things

What is the concentration effect? We have all seen the concentration effect occur in our daily lives. With a kitchen sink full of soapy water used to wash dishes, the more dishes you wash in the water, the dirtier the water gets, and the less effective it becomes at cleaning dishes. As the water in

Globally, rust is a significant problem. The United States Navy alone calls it a $6 billion problem. The National Association of Corrosion Engineers (NACE) put the cost at 276 billion dollars annually. It affects governments, businesses, and consumers alike. The best approach is to stop rust before it starts using one or multiple approaches such

Rust can be an ugly sight. But when it comes to the industries that rely on non-corroded metal to run, rust can also lead to some nasty consequences that aren’t always quite so visible: lack of productivity, accidents, and a significant financial loss. Companies are leaching billions of dollars out of their business each year

Hydrostatic testing of pressure vessels, such as pipes, heat exchangers, storage tanks, and ship voids, is essential for verifying the integrity of these components post-production and during use. This process demonstrates that the equipment can handle operational pressures safely, identifying any potential weak points needing repair. The procedure typically involves raising the internal pressure above

Part cleaning is an essential step in the manufacturing process, as precision metal parts typically have oils, greases, and other lubricants on the surface after the part is manufactured. These residues can prevent the adhesion of coatings and paints and accelerate corrosion if not properly removed. Manufacturers understand the importance of delivering clean parts in

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

Opening up a container to discover corrosion on metal items is frustrating. It often means lost time, missed deadlines, and unhappy people in your supply chain. The loss or rework of the corroded items plus the impact on business all total up to a significant cost. Corrosion can be complicated and may be caused by
