	Desiccants

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) (Measuring and Packaging) (Calculating Req.) Measuring Desiccants: A Unit of desiccant refers to its drying capacity, not its volume. The true definition is the quantity of desiccant required to meet the U.S. Military's specification (MIL-D-3464E) for packaged desiccant products. Under this specification, a unit is the quantity of desiccant which will adsorb 3.00 grams of water vapor at 20% relative humidity or 6.00 grams of water vapor at 40% relative humidity at 77°F (25°C). It may also be helpful to think of a unit as equating to approximately one ounce of material or 30 grams.
