Abstract

The method includes applying a fluorinated fluid to at least one of a surface of an object or an adhesive surface on an adhesive article, positioning the adhesive surface to face the surface of the object such that the fluorinated fluid is between the surface of the object and the adhesive surface; and removing at least some of the fluorinated fluid to permit bonding between the surface of the object and the adhesive surface. The fluorinated fluid generally facilitates the repositioning of the adhesive surface on the surface of the object before removing the fluorinated fluid. A kit comprising an adhesive article and a container including a fluorinated fluid is also described.

First claim

What is claimed is:

1. A method of making an article, the method comprising:
applying a fluorinated fluid to at least one of a surface of an object or an adhesive surface on an adhesive article;
positioning the adhesive surface to face the surface of the object such that the fluorinated fluid is between the surface of the object and the adhesive surface; and
removing at least some of the fluorinated fluid to permit bonding between the surface of the object and the adhesive surface to make the article.

2. The method of claim 1 , wherein the fluorinated fluid facilitates repositioning of the adhesive surface on the surface of the object before removing the fluorinated fluid.

3. The method of claim 1 , wherein the surface of the object is non-planar.

4. The method of claim 1 , wherein the surface of the object comprises at least one of metal, glass, a polymer, or a composite.

5. The method of claim 1 , wherein the article comprises at least one of a component of an electronic device or an aircraft.

6. The method of claim 1 , wherein the adhesive surface comprises a pressure sensitive adhesive.

7. The method of claim 6 , wherein the pressure sensitive adhesive is a natural rubber-, acrylic-, block copolymer-, silicone-, polyisobutylene-, polyvinyl ether-, or polybutadiene-based pressure sensitive adhesive.

8. The method of claim 1 , wherein the adhesive article comprises a film comprising at least one of polyester, polycarbonate, polyolefin, or acrylic onto which an adhesive is disposed to provide the adhesive surface.

9. The method of claim 1 , wherein the adhesive article is a bonding film, graphic film, anti-graffiti film, or an adhesive transfer tape.

10. The method of claim 1 , further comprising removing a release liner from the adhesive surface before positioning the adhesive surface to face the surface of the object such that the fluorinated fluid is between the surface of the object and the adhesive surface.

11. The method of claim 1 , wherein removing at least some of the fluorinated fluid comprises applying pressure to force at least some of the fluorinated fluid to flow out from between the adhesive surface and the surface of the object.

12. The method of claim 11 , wherein the pressure is applied to at least a portion of the adhesive article using a squeegee or roller.

13. The method of claim 1 , wherein removing at least some of the fluorinated fluid comprises evaporating the fluorinated fluid.

14. The method of claim 1 , wherein the fluorinated fluid comprises at least one of a hydrofluoroether, a hydrofluorocarbon, a hydrochlorofluorocarbon, a perfluorocarbon, a perfluoroketone, or a perfluoroolefin.

15. The method of claim 14 , wherein the fluorinated fluid comprises at least one of the hydrofluoroether, the perfluoroketone, or the perfluoroolefin.

16. The method of claim 1 , wherein the adhesive article is a bonding film or an adhesive transfer tape, the method further comprising:
applying a second fluorinated fluid to at least one of a surface of a second object or a second adhesive surface on the adhesive article;
positioning the second adhesive surface to face the surface of the second object such that the second fluorinated fluid is between the surface of the second object and the second adhesive surface of the adhesive article; and
removing at least some of the second fluorinated fluid to permit bonding between the surface of the second object and the second adhesive surface.

17. The method of claim 16 , wherein the second fluorinated fluid facilitates repositioning of the second adhesive surface on the surface of the object before removing the second fluorinated fluid.
