The present invention is a method of coating an adhesive layer. The method includes non-contact depositing a fluid solution onto the adhesive layer and allowing the fluid solution to substantially dry, where the fluid solution comprising a biological active. The fluid solution exhibits a Hildebrand solubility parameter of at least about 3.7 MegaPascals1/2 greater than a Hildebrand solubility parameter of the adhesive layer.
L'invention concerne un procédé permettant d'appliquer un revêtement sur une couche adhésive. Ce procédé consiste à déposer sans contact une solution de fluide sur la couche adhésive, et à laisser sécher sensiblement la solution de fluide, cette dernière contenant un principe actif biologique. La solution de fluide présente un paramètre de solubilité de Hildebrand supérieur d'au moins 3,7 MegaPascals1/2environ au paramètre de solubilité de Hildebrand de la couche adhésive.
