There is provided cured coating compositions derived from a one-part, moisture curable composition comprising (a) a polyoxyalkylene polymer having at least one end group derived from an alkoxy silane, and (b) a plasticizer selected from at least one of linear or branched alkyl benzoate having between 8 and 14 carbon atoms in the alkyl chain, and combinations thereof; where the cured coating composition passes ASTM D-1970. There are also provided articles and films made using and methods for using these cured coating compositions. L'invention concerne des compositions de revêtement durcies dérivées d'une composition à un constituant, durcissable à l'humidité comprenant (a) un polymère de polyoxyalkylène comportant au moins un groupe terminal dérivé d'un alcoxysilane, et (b) un plastifiant choisi parmi au moins un benzoate d'alkyle linéaire ou ramifié comprenant entre 8 et 14 atomes de carbone dans la chaîne alkyle, et des combinaisons de ceux-ci ; ladite composition de revêtement durcie satisfaisant à la norme ASTM D-1970. L'invention concerne également des articles et des films préparés en faisant appel aux dites compositions de revêtement durcies et des procédés d'utilisation de ces compositions de revêtement durcies.
