Desiccants in anti-corrosion packaging
Desiccants are used in anti-corrosion protection to reduce moisture in packaging and thus prevent corrosion of metal components.
Even in sealed anti-corrosion packaging, certain environmental conditions can lead to the formation of condensation, which settles on the metal surface before the VCI or ICB active agents do. In particular, when
packaging warm metal parts, condensation forms very quickly.
The EXCOR desiccant absorbs the moisture that occurs, thereby creating the conditions necessary for the inhibitors to exert their full protective effect on the metal surface.
Using desiccants correctly – protecting metal components
Desiccants only provide reliable protection against corrosion if they are used correctly within the packaging. Our desiccant also provides significant protection for metal parts with residual moisture in deep bores, packaging with a large air volume or long-term packaging. It is certified to DIN 55473.
Use of desiccants in packaging:
- No direct contact with metal surfaces
- Distribute as evenly as possible within the packaging space
- Seal the packaging to be water-vapour-tight, e.g. using a barrier film
When are desiccants used in addition to VCI or ICB?
Desiccant is used in addition when moisture acts more quickly than the corrosion protection provided by VCI or ICB.
Typical applications:
- Components packed whilst still warm (condensation)
- Residual moisture in components (e.g. in boreholes)
- High initial moisture content (e.g. in wooden packaging)
- Large packaging volume
- Long-term storage or export
Desiccants create the optimum conditions for VCI and ICB active ingredients to achieve their full protective effect.
