The present invention provides novel “patch in a bottle” technology in which a fluid composition, e.g., an aerosol spray, is applied onto a surface as a fluid, but then dries to form a covering element, such as a patch, having a tack free outer surface covering an underlying adhesive that helps adhere the patch to the substrate. The fluid compositions have a unique chemical formulation that allows such composite patches to form in situ. Specifically, the fluid compositions include a tacky component, such as an adhesive, and a film-forming, non-tacky component. The non-tacky and tacky components are selected to be immiscible with each other so that the components undergo phase separation as the fluid composition dries.
本发明提供了一种新型的“瓶中贴片”技术,其中将流体组成物(例如,气雾剂喷雾)作为流体涂在表面上,但随后干燥形成覆盖元素,例如贴片,其具有无粘性的外表面覆盖底层粘合剂,有助于将贴片粘附到基板上。流体组成物具有独特的化学配方,允许在原位形成这样的复合贴片。具体而言,流体组成物包括粘性组分,例如粘合剂,以及成膜、无粘性组分。非粘性和粘性组分被选择为互不相溶,因此随着流体组成物的干燥,这些组分会发生相分离。
