Zeolites

Zeolites

Definition

Zeolites are naturally occurring or synthetic microporous minerals used as desiccants to absorb and control moisture. They are commonly employed in conservation, packaging, and storage to protect sensitive materials from humidity damage.

Uses

• Reducing moisture in storage containers for artwork, documents, or collectibles.
• Maintaining stable relative humidity in display cases or shipping crates.
• Preventing mold, mildew, and other water-related damage to materials.

Properties

• Highly porous structure allows for efficient moisture adsorption.
• Non-toxic and chemically stable, safe for use with archival materials.
• Reusable after drying or regeneration under heat.

Installation Tips

• Place zeolites in breathable pouches or trays within storage or display areas.
• Monitor relative humidity and replace or regenerate zeolites as needed.
• Combine with silica gel for enhanced moisture control in high-humidity environments.
