Claims
- 1. A composition for coating, consisting essentially of a fluoroalkoxysilane and a hydrolyzed fluoroalkoxysilane in a water/alcohol solvent system, wherein said fluoroalkoxysilane contains an alkoxy moiety directly bonded to a silicon atom.
- 2. The composition of claim 1, wherein said fluoroalkoxysilane is a perfluoroalkylalkoxysilane having the formula: whereinm=0 to 15; n=1 to 5; p=0, 1, 2; each R is an alkyl, each R′ is an alkyl or H.
- 3. The composition of claim 1, further comprising a catalyst.
- 4. The composition of claim 2, wherein said catalyst is selected from the group consisting of a Bronsted acid and a Bronsted base.
- 5. The composition of claim 3, wherein said alcohol is selected from the group consisting of methanol, ethanol, butanol, isopropanol and mixtures thereof.
- 6. The composition of claim 3, wherein said water is present in an amount 3 to 20% by volume, based on said alcohol.
- 7. The composition of claim 3, wherein said fluoroalkoxysilane is a perfluoroalkylalkoxysilane having the formula: whereinm=0 to 15; n=1 to 5; p=0, 1, 2; each R is an alkyl, each R′ is an alkyl or H.
- 8. A process for making a coated substrate, comprising:applying the composition of claim 3 to a portion of a substrate.
- 9. The process of claim 8, wherein said applying is preformed at most 24 hours after preparation of said composition.
- 10. The process of claim 8, wherein said substrate is glass.
- 11. The product produced by the process of claim 10.
- 12. The product produced by the process of claim 8.
- 13. A process for making a composition for coating, consisting essentially of mixing(i) a fluoroalkoxysilane containing an alkoxy moiety directly bonded to a silicon atom, (ii) an aqueous/alcohol solvent system, and (iii) a catalyst.
- 14. The process of claim 13, wherein said catalyst is selected from the group consisting of a Bronsted acid and a Bronsted base.
- 15. The composition produced by the process of claim 13.
- 16. The composition of claim 15, wherein said alcohol is selected from the group consisting of methanol, ethanol, butanol, isopropanol and mixtures thereof.
- 17. The composition of claim 15, wherein said water is present in an amount 3 to 20% by volume, based on said alcohol.
- 18. The composition of claim 15, wherein said fluoroalkoxysilane is a perfluoroalkylalkoxysilane having the formula: whereinm=0 to 15; n=1 to 5; p=0, 1, 2; each R is an alkyl, each R′ is an alkyl or H.
- 19. A process for making a coated substrate, comprising:applying the composition of claim 15 to a portion of a substrate.
- 20. The process of claim 19, wherein said applying is preformed at most 24 hours after preparation of said composition.
- 21. The process of claim 19, wherein said substrate is glass.
- 22. The product produced by the process of claim 21.
- 23. The product produced by the process of claim 19.
