| A desiccant is a drying agent used to quickly reduce the humidity inside a closed container to a predetermined lower value, and then to maintain the humidity at that lower level for a period of time. A desiccant attracts moisture from the atmosphere and adsorbs and holds particles of water to itself. Commonly used during shipping or storage of products. ARMOR offers three types of desiccants, Clay, Silica Gel and Molecular Sieve. |

| Types of Desiccants |
| Clay |
| |
Most economical of all desiccants and highly effective within normal temperature and relative humidity ranges. |
| |
Used in most industrial applications requiring humidity control. Clay can adsorb up to 30% of its weight in water vapor at |
| |
77°F (25°C) and 80% relative humidity. |
| |
No apparent change in size, shape, or texture of the desiccant at full capacity.
|
| |
|
| Silica Gel (SiO2 * H2O) |
| |
Silica gel will adsorb about 40% of its weight in water vapor at 100% humidity. |
| |
Better suited than clay for temperatures above 120°F (49°C) as clay may give up moisture rather than pull it in. |
| |
Overall, high efficiency and high capacity desiccant. |
| |
|
| Molecular Sieve |
| |
Synthetically produced crystalline metal alumosilicate zeolite. |
| |
Good choice for the most demanding/unique applications. The pore structures provide a higher capacity for water |
| |
adsorption than clay or silica gel at very low humidity levels. |
| |
Retains a higher percentage of moisture capacity at elevated temperatures (well past 450°F) |
