a silane coupling agent comprising a perfluoropolyether group; and
a solvent comprising an alkane having a mean molecular weight of 138 to 180 g/mol and an alcohol.
2. The coating material of claim 1 , further comprising an accelerating agent.
3. The coating material of claim 1 , wherein the solvent further comprises a fluorinated solvent.
4. The coating material of claim 1 , wherein the alkane is an isoparaffin.
5. The coating material of claim 1 , wherein the alcohol is tert-butanol.
6. The coating material of claim 1 , wherein the alcohol is ethanol.
7. A product obtained by a process comprising applying the coating material of claim 1 to at least one surface of a glass layer.
8. The coating material of claim 2 , wherein the accelerating agent is hydrochloric acid.
9. The coating material of claim 8 , wherein a content of the hydrochloric acid in the coating material is 0.1 to 1.0 g/L.
10. The coating material of claim 3 , wherein the fluorinated solvent is a hydrofluoroether.
11. The coating material of claim 1 , wherein the alkane is at least one selected from the group consisting of a normal paraffin, an isoparaffin, and a cycloparaffin.
12. The coating material of claim 1 , wherein the alkane is a normal paraffin.
13. The coating material of claim 1 , wherein the alkane is a cycloparaffin.
14. The coating material of claim 1 , wherein the alcohol is at least one selected from the group consisting of n-butanol, isobutanol, sec-butanol, and tert-butanol.
15. The coating material of claim 1 , wherein the alcohol is at least one selected from the group consisting of ethanol, isopropanol, and tert-butanol.
16. The coating material of claim 1 , wherein the alcohol is isopropanol.
17. The coating material of claim 1 , wherein the agent has a formula (I):
18. The coating material of claim 1 , wherein the coating material is stain resistant.
19. The coating material of claim 4 , wherein the alcohol is tert-butanol.
20. The coating material of claim 4 , wherein the alcohol is ethanol.
21. The product of claim 7 , wherein the coating material enhances resistance of the glass to water comprising soluble silica and an oily component.
22. A product obtained by a process comprising applying the coating material of claim 17 to at least one surface of a glass layer.
23. The coating material of claim 17 , wherein the alcohol is at least one selected from the group consisting of n-butanol, isobutanol, sec-butanol, and tert-butanol.
24. The coating material of claim 17 , wherein the alcohol is at least one selected from the group consisting of ethanol, isopropanol, and tert-butanol.
