Abstract
Curable coating compositions and methods of coating the surfaces of objects, such as metal objects, are described. The coating compositions can include organic and/or inorganic solid adsorbent agents and provide durable cured coating layers on metal object surfaces that can be used to adsorb select molecules, such as carbon dioxide or water.
