Abstract

A conductive laminate product capable of dissipating static charges and adapted for use on vertical and horizontal surfaces. The laminate product is formed of a thin, hard layer of plastic material, a thin layer of metallic foil which is electrically conducted, bonded to the top layer by way of an electrically conducted adhesive material and a layer of backing material secured to the metallic foil.

Claims

1. As an article of manufacture, a conductive laminate product for application to flat surfaces including vertical and horizontal surfaces comprising in combination a layer of relatively thin, hard plastic material, a thin layer of metallic foil, an electrically conductive adhesive material positioned to bond the foil material to the plastic sheet, and a lamination of backing material secured to the metallic foil, the laminations being bonded together by being pressed together at temperature and pressure.

2. An article as in claim 1 wherein the metallic foil is aluminum foil.

3. An article as in claim 1 wherein the plastic sheet has a thickness of approximately 0.02 inches.

4. An article as in claim 3 wherein the metallic foil has a thickness in the range of approximately 0.007-0.015 inches.

5. An article as in claim 4 wherein the backing sheet is a layer of Kraft paper.

6. An article as in claim 1 wherein the electrically conductive adhesive material is a standard electrically conductive adhesive having in it electrolytic copper in the form of a powder.

7. As an article of manufacture, a conductive laminate product adapted for application to flat surfaces including vertical and horizontal surfaces comprising, in combination, a lamination of relatively thin, hard plastic material, a thin layer of metallic foil, and an electrically conductive adhesive material positioned to bond the foil to the plastic sheet, a lamination of backing material secured to the metallic foil layer, all of the laminations being bonded together by being subjected to pressure forcing them together and with the application of heat.

8. An article as in claim 7 wherein the plastic sheet has a thickness of approximately 0.020 inches.

9. An article as in claim 7 wherein the product is in the form of a sheet of a predetermined size, the said product having a self-adhesive back, the said back being covered by a removable cover sheet whereby to expose the adhesive so that the product can be directly stuck onto a flat surface.
