Abstract

A dual-adhesive double-sided adhesive tape, having a first double-sided tape that includes a first adhesive on each side of a first support and a second double-sided tape that has a second adhesive on each side of a second support. The first double-sided tape is attached to the release layer of the second double-sided tape. This dual-adhesive double-sided adhesive tape can be simply made by joining the first double-sided tape to a release layer of the second double-sided tape. The dual-adhesive double-sided adhesive tape of the present invention is suited for use in a method of mounting an article on a working surface. The article is provided with the dual-adhesive tape with the release liner of the first tape being removed so that the article can be temporarily mounted to determine the correct location before mounting the article by the second tape.

2. The dual-adhesive double-sided adhesive tape of claim 1, wherein each adhesive on the sides of the second double-sided tape has an adhesive strength that is greater than that of the adhesive on the first side of the first double-sided tape.

3. The dual-adhesive double-sided adhesive tape of claim 2, wherein the adhesives on each side of the second double-sided tape are the same pressure sensitive adhesives having the same adhesive strength.

4. The dual-adhesive double-sided adhesive tape of claim 1, wherein the adhesive on the second side of the first double-sided tape has an adhesive strength that is greater than the adhesive on the first side of the first double-sided tape.

5. The dual-adhesive double-sided adhesive tape of claim 4, wherein the adhesives of the first and second tapes are pressure sensitive adhesives and the adhesive strength of the adhesive on the second side of the second double-sided tape is greater by at least 20% as measured by surface energy compared to that of the adhesive on the first side of the first double-sided tape.

6. The dual-adhesive double-sided adhesive tape of claim 1, wherein the adhesive on the second side of the second double-sided tape has a greater amount of adhesive than that of the adhesive on the first side of the first double-sided tape.

7. The dual-adhesive double-sided adhesive tape of claim 1, wherein the adhesive on the second side of the second double-sided tape has a larger area of adhesive coverage than that of the adhesive on the first side of the first double-sided tape.

8. The dual-adhesive double-sided adhesive tape of claim 1, wherein the adhesive on the first side of the first double-sided tape is a silicone adhesive, the adhesive on the second side of the second double-sided tape is an acrylic based adhesive, and the support of the second double-sided tape includes an acrylic foam layer.

9. A method of making dual-adhesive double-sided adhesive tape of claim 1, comprising:

providing a first double-sided tape having a support that has first and second sides each coated with an adhesive, and with the adhesive on the first side including a release liner; and

providing a second double-sided tape comprising a support that has a first and second sides each coated with an adhesive, with the adhesive on the first side of the second double-sided tape including a release liner and with the adhesive on the second side of the second double-sided tape having (a) an adhesive strength that is greater than that of the adhesive on the first side of the first double-sided tape, (b) a greater amount of adhesive than that of the adhesive on the first side of the first double-sided tape, or (c) a larger area of adhesive coverage than that of the adhesive on the first side of the first double-sided tape; and

adhering the adhesive on the second side of the first double-sided tape to the release liner on the adhesive on the first side of the second double-sided tape.

10. The method of claim 9, wherein each adhesive on the sides of the second double-sided tape has an adhesive strength that is greater than that for the adhesive on the first side of the first double-sided tape.
