Articles subject to ice formation during normal use, are described comprising a repellent surface such that the receding contact angle of the surface with water ranges from (90) degrees to (135) degrees wherein the repellent surface comprises a siloxane material. In one embodiment, the repellent surface further comprises a non-fluorinated organic polymeric binder. In another embodiment, the repellent surface comprises a thermally processable polymer and a siloxane material melt additive. Also described are methods of making an article comprising providing an article subject to ice formation during normal use; and providing a liquid repellent surface, as described herein, on at least a portion of the article. L'invention concerne des articles soumis à la formation de glace en utilisation normale, comprenant une surface répulsive de telle sorte que l'angle de contact sortant de la surface avec de l'eau varie de (90) degrés à (135) degrés, la surface répulsive comprenant un matériau de siloxane. Dans un mode de réalisation, la surface répulsive comprend en outre un liant polymère organique non fluoré. Dans un autre mode de réalisation, la surface répulsive comprend un polymère pouvant être traité thermiquement et un additif de fusion de matériau siloxane. L'invention concerne en outre des procédés de fabrication d'un article consistant à fournir un article soumis à la formation de glace en utilisation normale et à fournir une surface repoussant les liquides, telle que ci-décrite, sur au moins une partie de l'article.
