CA 2601752

The invention described herein includes a repellent elastomeric article particularly useful in industrial and medical fields, such as gloves. The article contains an elastomeric base and a fluid-repellent coating composition that effectively repels both hydrophilic and lipophilic liquids from its surface. The coating comprises a low surface energy ingredient, such as a fluoroalkyl acrylic polymer. In a preferred embodiment, the low surface energy ingredient is in combination with a hydrophobic ingredient, such as a wax- based dispersion. Articles prepared in accordance with the invention reduce the risk of contamination associated with blood and other body fluids, as well as reduce fluid-based visual obstruction and enhance the clarity of medical procedures. The invention also provides a fluid-repellent coating composition for elastomeric articles, a process for preparing a fluid-repellent elastomeric article, and a method of reducing the ability of fluids to adhere to the surface of an elastomeric article.

L'invention porte sur un article d'élastomère hydrophobe et lipophobe particulièrement utile dans les domaines de l'industrie et de la médecine, tel que des gants. Un tel article comprend une base d'élastomère et un revêtement repoussant les fluides hydrophiles et lipophiles de sa surface. Ledit revêtement comporte un ingrédient à faible tension superficielle tel qu'un polymère acrylique de fluoroalkyle. Dans l'exécution préférée, ledit ingrédient est combiné à un ingrédient hydrophobe tel qu'une dispersion à base de cire. Les articles conformes à l'invention réduisent les risques de contamination associés au sang et à d'autres fluides corporels ainsi que le masquage visuel, ce qui améliore la visibilité dans les actes médicaux. L'invention porte également: sur la composition du revêtement pour articles élastomères, sur le procédé de réalisation d'un article en élastomère repoussant les fluides, et sur un procédé de réduction de la capacité d'adhérence de fluides à la surface d'articles d'élastomère.
