Abstract

A high temperature resistant masking device (10) comprising a substrate having a top surface (26) and a bottom surface (28) with an adhesive applied to the bottom surface (28) of the substrate for removable attachment to a masking surface. The masking device (10) includes a pull tab (12) extending upwardly from the device'"'"'s center portion for facilitating easy placement and removal of the masking device (10) from the masking surface. The masking devices (10) are die-cut into various shapes and sizes, and placed on rolls of release liner so that they may be readily applied to parts requiring masking during a painting or coating process.

Claims

1. A device for masking a surface including an upwardly-extending tab for gripping the masking device, comprising:

a two-piece masking-device substrate having a top surface and a bottom surface, said masking-device substrate comprising;

a first discrete substrate element having a fold line defining a base portion surface; and

a first upwardly-extending side member portion including a first surface;

a second discrete substrate element having a fold line defining a base portion and a second upwardly extending side member portion including a second surface, said side member portions being configured and arranged such that the side member portion first and second surfaces abut one another; and

an adhesive on the abutting side member portion first and second surfaces, said adhesive joining the first and second discrete substrate elements such that the side member portions form the gripable tab extending upwardly from the masking-device substrate top surface; and

an adhesive on the masking-device substrate bottom surface, said adhesive selected such that the masking-device substrate is removable from a surface to which the masking device is attached.

2. The masking device of claim 1, wherein the adhesive is selectively located on only a portion of the side member portion first and second surfaces.

3. The masking device of claim 2, wherein the adhesive is a silicone adhesive.

4. The masking device of claim 2, wherein the adhesive is a rubber based adhesive.

5. The masking device of claim 1, wherein the masking-device substrate is die-cut from sheet material into predetermined shapes and sizes.

6. The masking device of claim 1, further including a release liner having a surface and the masking device is removably attached to the release liner surface.

7. The masking device of claim 1, wherein the tab formed by the first and second side member portions extends upwardly from a center portion of the masking-device substrate.

8. The masking device of claim 1, wherein the substrate is made of a material selected from the group consisting of crepe paper, vinyl, polyester, mylar and kapton.

9. The masking device of claim 1, wherein the masking-device substrate is adapted to withstand temperatures of approximately 200 to 600 degrees Fahrenheit.

18. The masking device of claim 1 wherein the adhesive joining the abutting side member portion first and second surfaces and the adhesive on the substrate bottom surface are identical adhesive materials.

10. A masking device comprising:

a two-piece substrate comprising first and second discrete substrate elements bonded together, the two-piece substrate having a top surface and a bottom surface;

an adhesive on the two-piece substrate bottom surface, said adhesive permitting removable attachment of the two-piece substrate on a masking surface; and

a tab for gripping the masking device, said tab extending upwardly from the two-piece substrate top surface and comprising bonded-together portions of the first and second discrete substrate elements.

11. The masking device of claim 10, further including a release liner having a surface and the making device is removably attached to the release liner surface.

12. The masking device of claim 10, wherein the tab comprises a first discrete substrate element first side member portion and a second discrete substrate element second side member portion, the side member portions having a top surface and a facing surface, the side members being bonded together along their facing surfaces by an adhesive on said facing surfaces.

13. The masking device of claim 12, wherein the first side member portion comprises a region of the first discrete substrate element defined by a fold line and the second side member portion comprises a region of the second discrete substrate element defined by a further fold line.

14. The masking device of claim 10, wherein the two-piece substrate is die-cut from sheet material into predetermined shapes and sizes.

15. The masking device of claims 10, wherein the tab extends upwardly from a center portion of the two-piece substrate.

16. The masking device of claim 10, wherein the two-piece substrate is made of a material selected from the group consisting of crepe paper, vinyl polyester, mylar and kapton.

17. The masking device of claim 10, wherein the two-piece substrate can withstand temperatures of approximately 200 to 600 degrees Fahrenheit.

19. A masking device comprising:

a two-piece masking-device substrate having a top surface, a bottom surface and a tab projecting from the top surface, said substrate comprising;

a first discrete substrate element having a fold line defining a base portion and a first side member portion including a bottom surface; and

a second discrete substrate element having a fold line defining a base portion and a second side member portion including a bottom surface, said first and second side member portion bottom surfaces being joined together to form the masking-device substrate and the tab projecting therefrom; and

an adhesive on the masking-device substrate bottom surface, said adhesive selected such that the masking-device substrate is removable from a surface to which the masking device is attached.

20. The masking device of claim 19, further including an adhesive on at least one of the first and second side member portion bottom surfaces, said adhesive joining together the first and second side member portion bottom surfaces.

21. The masking device of claim 20, wherein the adhesive is a silicone adhesive.

22. The masking device of claim 20, wherein the adhesive is a rubber based adhesive.

23. The masking device of claim 19 further including a release liner and the masking device substrate is removably attached to the release liner.

24. The masking device of claim 19, wherein the tab formed by the joined together first and second side member portion bottom surfaces extends upwardly from a center portion of the masking device substrate.

25. The masking device of claim 19, wherein the first and second discrete substrate elements are each made of a material selected from the group consisting of crepe paper, vinyl, polyester, mylar and kapton.
