Corrosion is the gradual degradation of metal surfaces due to environmental factors such as water, oxygen or humidity. It most commonly appears as rust.
VCI (Volatile Corrosion Inhibitor) is a technology that protects metals from corrosion. VCI products release vapor-phase inhibitors that migrate through the air and form a thin, invisible molecular layer on metal surfaces. This layer blocks moisture and oxygen, preventing them from reacting with the metal and causing corrosion.
Unlike oils or greases, VCI requires no surface cleaning and offers clean, contact-free protection. It's also safer for human health and the environment.
With proper application and suitable storage conditions (such as sealed packaging and controlled humidity), VCI products can provide effective corrosion protection for 1 to 5 years. The exact duration depends on the type of VCI product, the environment, and how well the packaging is maintained.
Moisture damage occurs when water vapor enters or condenses inside packaging, leading to problems such as corrosion on metal surfaces or mold, rot, and degradation in organic materials like paper, textiles, or food. It is a common risk in poorly sealed or improperly stored products.
Container rain is caused by condensation inside shipping containers due to temperature changes. It can damage products through corrosion, mold, or packaging failure. Using the right amount of desiccants helps control humidity and prevent moisture-related risks during transit.
Desiccants are materials that adsorb or absorb moisture from the air inside a package. By reducing humidity levels, they help keep the internal environment dry and protect products from moisture-related damage such as corrosion, mold, or spoilage.
The required amount of desiccant depends on factors such as product volume, ambient humidity, packaging materials, and shipping duration. The TRUGUARD technical team can assist in calculating the optimal quantity for effective moisture protection.
Desiccants alone may not be sufficient in high-humidity environments or when metal corrosion protection is required. In such cases, it is recommended to combine desiccants with VCI technology for more effective and comprehensive protection.
Absolutely. Corrosion and moisture damage cause more than just physical harm—they can lead to financial losses, production delays, and damage to brand reputation, making effective protection essential.
