A first aspect of the present invention is directed to a surface treatment for elastomeric articles such as medical gloves, comprising a water-based coating formulation and antimicrobial agent(s) embraced therein in an essentially powder-free composition coating. A second aspect of the present invention is directed to a water-based coating formulation for elastomeric articles such as gloves comprising at least one non-volatile water-soluble antimicrobial agent in a controlled-release matrix comprising a blend of a hydrophilic polymer and a hydrophobic component. The controlled-release matrix/blend requirements include: compatibility with the antimicrobial agent, formation of a reservoir of antimicrobial agent, coating film flexibility and lower water-solubility than the antimicrobial agent. A third aspect of the present invention is directed to a method for treating medical gloves comprising dipping, spraying, tumbling or other means for applying to the glove surface a composition to provide medical gloves with sustainable antimicrobial activity.

La présente invention concerne, dans un premier aspect, un traitement de surface pour des objets élastomères tels que des gants médicaux, comprenant une formulation de revêtement à base d~eau et un ou plusieurs agents antimicrobiens contenus à l'intérieur de celle-ci dans un revêtement de composition sensiblement dépourvu de poudre. Un deuxième aspect de la présente invention concerne une formulation de revêtement à base d~eau pour des objets élastomères tels que des gants comprenant au moins un agent antimicrobien soluble dans l~eau non volatil dans une matrice à libération contrôlée comprenant un mélange d~un polymère hydrophile et d~un composant hydrophobe. Les exigences de ladite matrice/dudit mélange comprennent : une compatibilité avec l~agent antimicrobien, la formation d~un réservoir dudit agent, une souplesse du film de revêtement et une solubilité dans l~eau inférieure audit agent. Un troisième aspect de la présente invention concerne un procédé pour traiter des gants médicaux comprenant le trempage, la pulvérisation, le culbutage ou d~autres moyens pour appliquer à la surface des gants une composition fournissant auxdits gants une activité antimicrobienne durable.
