Patent ID: 7691288

Claim:
A process for making a screen-printable getter paste composition, comprising 50-80 weight % of inorganic solids and 20-50 weight % of an organic medium, said process comprising: dispersing glass frit and a desiccant material selected from the group consisting of zeolites, alkaline earth metal oxides, sulfates, chlorides and bromides in an organic medium comprised of organic polymeric binder and volatile organic solvent, wherein said desiccant material is pre-hydrated to reach its saturation level of moisture absorption prior to its being dispersed in said organic medium; wherein said desiccant material is hydrated by exposing said material in an ordinary paste production environment to reach pseudo steady state weight gain due to the moisture absorption or wherein said desiccant is hydrated by exposing the material in a controlled temperature and humidity environment to reach pseudo steady state weight gain due to the moisture absorption.
