Abstract

Various tags and adhesive labels are described which can be used in high temperature environments such as up to 1,000° C. The tags and labels include a substrate having one or more high temperature printable coatings. The labels can also include pressure sensitive adhesives and optional release liners.

First claim

What is claimed is:

1. A printable tag for high temperature applications, the tag comprising:
a coated substrate defining at least one print receptive face, the coated substrate having a high temperature printable coating that constitutes the print receptive face, wherein the coating comprises pigment dispersed in a binder comprising silicate/phosphate, and wherein the coating does not comprise a siloxane binder.

2. The tag of claim 1 wherein the substrate includes at least one material selected from the group consisting of polymeric materials, metal materials, coated cloth materials, and composites thereof.

3. The tag of claim 2 wherein the substrate includes at least one polymeric material.

4. The tag of claim 3 wherein the polymeric material is polyimide.

5. The tag of claim 2 wherein the substrate includes at least one metal material.

6. The tag of claim 5 wherein the metal material is selected from the group consisting of aluminum, aluminum alloy, stainless steel alloy, and combinations thereof.

7. The tag of claim 1 wherein the substrate has a single substrate layer.

8. The tag of claim 1 wherein the substrate is a multilayer substrate.

9. The tag of claim 8 wherein the multilayer substrate has a total number of substrate layers of from 2 to 4.

10. The tag of claim 1 wherein the coating exhibits a heat resistance at a temperature within a range of from 500° C. to 1,000° C.

11. A printable adhesive label for high temperature applications, the label comprising:
a substrate defining a first face and an oppositely directed second face;
a pressure sensitive adhesive disposed on the second face of the substrate;
a high temperature printable coating disposed on the first face of the substrate, wherein the coating comprises pigment dispersed in binder comprising silicate/phosphate, and wherein the coating does not comrprise a siloxane binder.

12. The label of claim 11 wherein the substrate includes at least one material selected from the group consisting of polymeric materials, metal materials, coated cloth materials, and composites thereof.

13. The label of claim 12 wherein the substrate includes at least one polymeric material.

14. The label of claim 13 wherein the polymeric material is polyimide.

15. The label of any claim 12 wherein the substrate includes at least one metal material.

16. The label of claim 15 wherein the metal material is selected from the group consisting of aluminum, aluminum alloy, stainless steel alloy, and combinations thereof.

17. The label of claim 11 wherein the substrate has a single substrate layer.

18. The label of claim 11 wherein the substrate is a multilayer substrate.

19. The label of claim 18 wherein the multilayer substrate has a total number of substrate layers of from 2 to 4.

20. The label of claim 11 wherein the coating exhibits a heat resistance at a temperature within a range of from 500° C. to 1,000° C.

21. A method of labeling a surface having a temperature within a range of from 500° C. to 1,000° C., the method comprising:
providing a label including (i) a substrate defining a first face and an oppositely directed second face, (ii) a pressure sensitive adhesive disposed on the second face of the substrate, and (iii) a high temperature printable coating disposed on the first face of the substrate, wherein the coating comprises pigment dispersed in a binder comprising silicate/phosphate, and wherein the coating does not comprise a siloxane binder; and
applying the label to a surface having a temperature within a range of from 500° C. to 1,000° C.

22. The method of claim 21 wherein the applying is performed by contacting the pressure sensitive adhesive of the label to the surface.

23. The method of claim 21 wherein the substrate includes at least one material selected from the group consisting of polymeric materials, metal materials, coated cloth materials, and composites thereof.

24. The method of claim 23 wherein the substrate includes at least one polymeric material.

25. The method of claim 24 wherein the polymeric material is polyimide.

26. The method of claim 23 wherein the substrate includes at least one metal material.

27. The method of claim 26 wherein the metal material is selected from the group consisting of aluminum, aluminum alloy, stainless steel alloy, and combinations thereof.

28. The method of claim 21 wherein the substrate has a single substrate layer.

29. The method of claim 21 wherein the substrate is a multilayer substrate.

30. The method of claim 29 wherein the multilayer substrate has a total number of substrate layers of from 2 to 4.

31. The method of claim 21 wherein the coating exhibits a heat resistance at a temperature within a range of from 500° C. to 1,000° C.

32. A method of providing identification of a component subjected to a temperature up to 1,000° C., the method comprising:
providing an adhesive label including (i) a substrate defining a first face and an oppositely directed second face, (ii) a pressure sensitive adhesive disposed on the second face of the substrate, and (iii) a high temperature printable coating disposed on the first face of the substrate, wherein the coating comprises pigment dispersed in a binder comprising silicate/phosphate, and wherein the coating does not comprise a siloxane binder;
printing identification indicia on the coating; and
contacting the pressure sensitive adhesive with the component.
