Beschreibung
Zusammenfassung:	Embodiments of the present disclosure are directed to coating compositions, coated articles, and methods in which the coated article is adapted to exhibit a particular permeance profile, such as, for example, a variable water vapor perm rating of about 1 perm or less at 25% average RH and about 15 perms or more at 95% average relative humidity, as tested by ASTM E96 at 21 C. Des modes de réalisation de la présente invention portent sur des compositions de revêtement, des articles revêtus et des procédés dans lesquels l'article revêtu est adapté pour présenter un profil de perméance particulier, tel que, par exemple, un indice variable de perméance à la vapeur d'eau, mesuré selon la norme ASTM E96 à 21 °C, inférieur ou égal à environ 1 perme à une humidité relative (HR) moyenne d'environ 25 % et supérieur ou égal à environ 15 permes à une HR moyenne de 95 %.
