Abstract

See full text

Certain embodiments described herein are directed articles that include a cellulosic substrate (or a non-cellulosic substrate) and an aqueous dispersion disposed on the substrate. In certain examples, the dispersion is effective to provide a water vapor perm rating of about 2 perms or less at 25% average RH as tested by ASTM D1653, or about 2 perm or less at 25% average RH as tested by ASTM E96, when the dispersion is cured as a coating on the substrate. In some embodiments, the substrate can be (or can be part of) a building substrate such as, for example, kraft paper placed on insulation (e.g., fiberglass insulation) or oriented strand board. In some instances, the aqueous dispersion can include a plant oil macromonomer or a waterborne epoxy resin.
