Abstract

Adsorbent bed coating for use on a metallic surface includes a powder-like solid adsorbent bed with a grain diameter between 1 and 50 .mu.m bonded by a finely dispersed binder agent with a mass component of less than 50% with respect to the powder component. The thickness of the adsorbent bed coating on the metallic surface is less than 4 mm such that the adsorption speed of water vapor at a steam pressure of less than 20 mbar results in a weight increase of at least 5% (with respect to the adsorbent bed) within 30 minutes.
