Montmorillonite Clay Desiccant

• Montmorillonite Clay is the least expensive of all

desiccants and is a naturally occurring non-hazardous mineral

• Montmorillonite Clay is used in most industrial applications requiring humidity control because it recharges easily and does not swell as it adsorbs water vapor.

• This desiccant works well at low and room temperatures, but has a low ceiling temperature. 

– At 120º F montmorillonite clay will begin to desorb or shed the moisture it has absorbed, an important consideration for storage in hot areas.

• Desiccants on their own can be extremely effective, although they work better when used in combination with moisture barrier bags.

• Different moisture barrier bag materials come with different MVTR ratings.

• The most effective moisture barrier bag material has an MVTR rating of 0.02, meaning that only 0.02 grams of moisture can penetrate the material over a 24-hour period in 95 percent humidity.
