ABSTRACT:
A method of selecting an appropriate resin bonded sorbent composition which may be used at least for in part making an enclosure to protect contents from external humidity including the steps of: a) selecting a plurality of resins, a plurality of sorbents and a plurality of ratios therebetween to form a plurality of composites; b) calculating a plurality of failure times for the plurality of composites, wherein each failure time of the plurality of failure times is based on when an internal relative humidity of each composite of the plurality of composites is equal to the maximum internal relative humidity; c) determining which of the plurality of failure times is greater; and, d) selecting one composite of the plurality of composites based on the result of step (c).
