ABSTRACT:
High potassium zeolite A particles are used to overcome problems of zeolite degassing (and/or undesired gas adsorption/desorption), especially when loaded into organic matrices. The zeolite A particles preferably have a potassium content (measured as K.sub.2 O) of at least about 14 wt. %, more preferably 15-25 wt. %. Compositions containing the high potassium zeolite A in an organic matrix may be especially suitable for use in insulating glass window spacer applications. The high potassium zeolite A may also be used in other conventional desiccant forms.
