Abstract

Methods of manufacturing and coating glass including depositing an inorganic oxide on an exterior surface of the glass, and then applying an organofunctional silane to the glass over the inorganic oxide. The methods also may include applying an organic coating to the glass over the organofunctional silane, and curing the organic coating.

Claims

1. A method of coating glass, which includes the steps of:

(a) depositing an inorganic oxide on the glass, and then

(b) applying an organofunctional silane to the glass over the inorganic oxide.

2. The method set forth in claim 1 wherein said step (a) is carried out by flame pyrolysis.

3. The method set forth in claim 1 wherein the inorganic oxide of said step (a) is SiO₂.

4. The method set forth in claim 1 further including the step of:

(c) applying an organic coating to the glass after step (b), over the organofunctional silane.

5. The method set forth in claim 4 further including the step of:

(d) curing said organic coating.

6. The method set forth in claim 1 including the step, prior to said step (a), of applying a cold end coating to the glass.

7. The method set forth in claim 1 including the step, prior to said step (a), of applying a hot end coating to the glass.

8. The method set forth in claim 1 including the steps, prior to said step (a), of applying a hot end coating to the glass and then a cold end coating to the glass, and inspecting the glass.

9. A method of manufacturing a glass container, which includes the steps of:

(a) forming the glass container,

(b) applying a hot end coating to an exterior surface of the glass container,

(c) annealing the glass container,

(d) applying a cold end coating to the exterior surface of the glass container,

(e) inspecting the glass container, and then

(f) depositing an inorganic oxide on the exterior surface of the glass container, and

(g) applying an organofunctional silane to the glass container over the inorganic oxide.

10. The method set forth in claim 9 wherein said step (f) is carried out by flame pyrolysis.

11. The method set forth in claim 9 wherein the inorganic oxide of said step (f) is SiO₂.

12. The method set forth in claim 9 further including the steps of:

(h) applying an organic coating to the glass container after step (g), over the organofunctional silane, and then

(i) curing said organic coating.

13. A method of coating a glass container, which includes the steps of:

(a) depositing an inorganic oxide on an exterior surface of the glass container,

(b) following said step (a), applying an organofunctional silane to the glass container over the inorganic oxide, and then

(c) applying an organic coating to the glass container over the organofunctional silane.

14. The method set forth in claim 13 wherein said step (a) is carried out by flame pyrolysis.

15. The method set forth in claim 14 further including the step of:

(d) curing said organic coating.

16. The method set forth in claim 15 including, prior to said step (a), at least one additional step of at least one of applying a hot-end coating to the glass container or applying a cold end coating to the glass container.

17. The method set forth in claim 16 wherein said hot-end coating is SnO₂.

18. The method set forth in claim 13 wherein said inorganic oxide is a silicon-based inorganic oxide.

19. The method set forth in claim 18 wherein said silicon-based inorganic oxide is SiO₂.
