Disclosed is an elastomeric article, such as an elastomeric glove, for example, and a method for making the disclosed elastomeric article. The elastomeric article includes a fluorocarbon graft on the donning surface of the article. In addition, a hydrophilic lubricant including a modified siloxane displaying polar functionality may be applied to the surface of the article. In one embodiment, the modified siloxane may be an amino modified siloxane. The silicone lubricant and the fluorocarbon graft display a synergy, providing an article with improved dry slip characteristics and improved wet slip characteristics. In addition, a fatty alcohol may be applied to the surface of the article, further improving the damp slip characteristics of the article.

L'invention concerne un article en élastomère, tel qu'un gant en élastomère, par exemple, ainsi que son procédé de fabrication. La surface interne de l'article est recouverte d'un enduit au fluorocarbone. De plus, un lubrifiant hydrophile contenant un siloxane modifié à fonctionnalité polaire peut être appliqué sur la surface de l'article. Dans un mode de réalisation, le siloxane modifié peut être un siloxane modifié amino. L'utilisation conjointe du lubrifiant siliconé et de l'enduit au fluorocarbone permet d'obtenir un article qui glisse davantage, d'une part, dans un environnement sec et, d'autre part, dans un environnement humide. Par ailleurs, un alcool gras peut être appliqué sur la surface de l'article pour améliorer davantage les caractéristiques décrites ci-dessus.
