Metal products are susceptible to corrosion in humid environments. When metal is exposed to moist air, water molecules create a thin film on the metal surface. This film acts as an electrolyte, enabling electrochemical reactions between oxygen in the air and the metal surface. These reactions result in the formation of oxides or hydroxides on the metal, commonly referred to as "rust." Different types of metals demonstrate varying degrees of corrosion resistance in damp conditions, but most are vulnerable to some extent.
Moisture-related issues: rust, spotting, surface discolouration and functional failure of metal components.
Moisture Prevention Recommendations
Place calcium chloride desiccant inside the packaging to promptly absorb any excess moisture.
Regularly monitor and control warehouse temperature and humidity to keep relative humidity within specified limits.
Container desiccants are installed in shipping containers to absorb excess moisture and prevent container condensation during transit.
