SELECTIVELY PERMEABLE ZEOLITE ADSORBENTS AND SEALANTS MADE THEREFROM

The invention relates to an improved adsorbent, essentially impermeable to oxygen and nitrogen but permeable to water vapor, and to sealants incorporating said adsorbent. The adsorbent comprises outgassed zeolite having pores with apertures large enough to permit entry of gases such as oxygen and ni...

Beschreibung
Zusammenfassung:	The invention relates to an improved adsorbent, essentially impermeable to oxygen and nitrogen but permeable to water vapor, and to sealants incorporating said adsorbent. The adsorbent comprises outgassed zeolite having pores with apertures large enough to permit entry of gases such as oxygen and nitrogen into the pore spaces and having on its surface, covering the pore apertures, a fluid which is essentially impermeable to nitrogen and oxygen molecules and yet permeable to water vapor. The zeolite adsorbent, and sealants prepared from the zeolite, are particularly useful in the fabrication of thermal insulating glazed windows having a sealed air pocket.
