Abstract

A seal splice or tape comprising a carrier having an adhesive construction on the opposite side thereof. The adhesive construction comprises an adhesive coating on the carrier layer with a release agent and liner thereover. The adhesive coat extending from end to end on one side and only part way inboard on the opposite side. In a preferred embodiment, the carrier is scored near the end having adhesive on both ends to permit both layers of the liner to be removed essentially simultaneously or otherwise.

Claims

1. A splice article including a carrier having an adhesive construction on its opposite sides, said adhesive construction including an adhesive coating on said opposite sides, on one side the coating extends essentially from end to end and on the other side extends from an end inboard a sufficient distance to give desired overlap on installation of said article, a release agent covering said adhesive coat on each side of the carrier, and a release liner on said release agent, said carrier having a score line near the end containing adhesive on its opposite sides and there is no release agent between that end and the score line on the side where adhesive does not extend from end to end.

2. The seal article of claim 1 wherein the adhesive coat is a pressure sensitive one.

3. A splice article including a carrier having an adhesive construction on its opposite sides, said adhesive construction including an adhesive coating on said opposite sides, on one side the coating extends essentially from end to end and on the other side extends from an end inboard a sufficient distance to give desired overlap on installation of said article, a release agent covering said adhesive coat on each side of the carrier, and a release liner on said release agent, said adhesive applied to one side being different from that applied to the opposite side.

4. The article of claim 3 wherein the different adhesives can react with each other to form an enhanced bond.

5. An article having a score line near at least a longitudinal end thereof to form a scored section and having an adhesive construction on each side thereof, the adhesive construction on one side comprising a layer of adhesive covered with a release agent and release liner and on the other side having an adhesive layer extending over the scored section inboard past the score line and having a release agent on said adhesive layer extending inboard from score line and a release liner covering said release agent and the scored section.

6. The article of claim 5 wherein the adhesive coat is a pressure sensitive one.

7. The article of claim 5 wherein the adhesive applied to one side is different from that applied to the other side.

8. The article of claim 7 wherein the different adhesives can react with each other to form an enhanced bond.

9. The article of claim 5 wherein the release liner extends past the release agent to form a pull tab.

10. A method of making a splice composition comprising without sequence (a) coating one side of a carrier with a coat of adhesive and applying over said coat a release agent and a release liner to protect said coat and (b) coating the opposite side of said carrier from one end inboard aways with an adhesive and applying over said adhesive on this side a release agent and a release liner, said liner extending beyond said release agent sufficient to provide a tab for removal of said liner.

11. The method of claim 10 wherein the splice composition is slit or cut into strips to form a splice strip.

12. The method of claim 10 wherein the adhesive applied to one side is different from that applied to the opposite side.

13. The method of claim 10 wherein the different adhesives effect an enhanced bond between overlapping ends.

14. The method of claim 10 wherein the carrier is scored at a slight distance from the end that adhesive extends only inboard aways and before said release liner is applied to each side having adhesive extending only inboard aways.

15. An adhesive member including a carrier having a layer of adhesive covered with a release liner on one side and an adhesive layer on a portion of the other side to permit the end of said member in installation to overlap and bring the layers of adhesive into overlapping contact said adhesive applied to one side being different from that applied to the other side.

16. The adhesive member of claim 15 wherein the adhesive applied to one side is different from that applied to the other side.

17. The adhesive member of claim 15 wherein the different adhesives or adhesive percursors can react with each other to form an enhanced bond.

18. The adhesive member of claim 15 wherein the carrier has a reflective face.

19. The adhesive member of claim 15 wherein the reflective face is aluminum.
