DESICCANT COMPOSITION CONTAINING SURFACE-MODIFIED POWDERS OF METAL OXIDES USEFUL FOR MANUFACTURE AND PROTECTION OF MOISTURE-SENSITIVE DEVICES

摘要

A desiccant composition is described. The desiccant composition has a polymeric binder and a dispersion of powders of hygroscopic inorganic oxides as desiccant materials, in which the desiccant powders are finely dispersed in consequence of their surface-modification by fatty acid anions without affecting their moisture sorption performances.
