Activated Clay desiccant is a low-cost, efficient desiccant which will protech the contents of a properly sealed container until it is opened. The contents of a sealed container will be in the same condition as when packaged for shipment or storage. Activated Clay unit bags exceed the requirements of Mil-D-3464E in actual performance and will exceed the moisture vapour adsorption of silica gel at government specifications levels. Activated Clay montmorillonite clay is a naturally occurring mineral as opposed to the chemically synthesized adsorbent. Therefore it is more economical than silica gel or molecular sieve.
