How do Valdamark VCI products help to prevent corrosion?

Valdamark VCI products utilise VCI technology to protect metal components from corrosion and degradation.

VCI molecules are attracted to metal surfaces, causing them to react and form a barrier against humidity, oxidation, and other corrosive agents. Valdamark VCI products can be applied directly to the surface of metals or used as packaging material for shipping protection.VCI products play an important role in protecting metal surfaces from corrosion.

VCI products emit volatile corrosion inhibitors (VCIs) that passivate the electron flow between anodic and cathodic areas on metal surfaces, interrupting the electrochemical corrosion process. VCI products also contain water-repellent properties that prevent water from permeating the metal surface and providing the electrolyte for corrosion reactions. In this way, VCI products provide an effective barrier against external corrosive elements, such as abrasion, water, dirt, and acid gas pollutants.

VCI products release a corrosion-inhibiting vapor that diffuses throughout an enclosure and settles on exposed metal surfaces. VCI materials are absorbed onto the surface of the metal to form a corrosion-inhibiting protective layer. This VCI layer is just a few molecules thick and helps to prevent corrosion. VCI-treated materials have a long shelf life and can be used repeatedly. VCI products are an effective and safe way to prevent corrosion.

The Valdamark VCI products are an effective way to protect metal content from corrosion because they may include acid gas-absorbing chemicals in the packaging material. These “scavenging” substances react with polluted air that may diffuse through these materials, neutralising it and providing extra protection for your valuable assets!

Also used are various combinations of physical barrier properties that optimize the corrosion prevention and physical protection needs of our customers. These may range from plain low-density polyethylene (LDPE) material to combinations of higher strength, higher tear resistance, higher resistance to sunlight or UV, static charge dissipation, and lower diffusion for moisture or acid gas molecules.
