Abstract

A method for providing a metallic coating on glass strands or organically precoated glass strands comprising the steps of coating the glass strand (or organically precoated glass strand) with a metallorganic material, heating the metallorganically coated glass strand (or organically precoated glass strand) to a temperature sufficient to degrade the metallorganic material and drive off the organic portion thereby leaving a metallic coating behind, and cooling the now metal coated glass strand (or organically precoated glass strand) to a useful temperature.

Claims (18)

1. A method for metal coating a glass strand comprising the steps of coating at least one portion of the glass strand with a metallorganic material, heating the metallorganically coated glass strand to a temperature sufficient to degrade the metallorganic material and drive off the organic portion thereby leaving a thin metallic coating on the glass strand, and cooling the metal coated glass strand.

2. The method according to claim 1 wherein the glass strand is coated with an organic material prior to the step of coating with a metallorganic material.

3. The method according to claim 2 wherein the step of heating the metallorganically coated glass strand is accomplished using an infrared heater.

4. The method according to claim 3 wherein the metal in the metallorganic material is selected from the group consisting of gold, silver, platinum and palladium.

5. The method according to claim 4 wherein the metallorganic coats the entire strand.

6. The method according to claim 2 wherein the step of heating the metallorganically coated glass strand is accomplished using a laser light source.

7. The method according to claim 6 wherein the metal in the metallorganic material is selected from the group consisting of gold, silver, platinum and palladium.

8. The method according to claim 7 wherein the metallorganic coats the entire strand.

9. The method according to claim 2 wherein the metal in the metallorganic material is selected from the group consisting of gold, silver, platinum and palladium.

10. The method according to claim 9 wherein the metallorganic coats the entire strand.

11. The method according to claim 1 wherein the step of heating the metallorganically coated glass strand is accomplished using an infrared heater.

12. The method according to claim 11 wherein the metal in the metallorganic material is selected from the group consisting of gold, silver, platinum and palladium.

13. The method according to claim 12 wherein the metallorganic coats the entire strand.

14. The method according to claim 1 wherein the step of heating the metallorganically coated glass strand is accomplished using a laser light source.

15. The method according to claim 14 wherein the metal in the metallorganic material is selected from the group consisting of gold, silver, platinum and palladium.

16. The method according to claim 15 wherein the metallorganic coats the entire strand.

17. The method according to claim 1 wherein the metal in the metallorganic material is selected from the group consisting of gold, silver, platinum and palladium.

18. The method according to claim 17 wherein the metallorganic coats the entire strand.
