Abstract
The present invention concerns a method for treating the surface of glass, a substrate comprising a glass surface treating with the inventive method and the use of the substrate.
Claims18
A method for treating at least one glass surface, the method comprising:
- a) providing a substrate comprising the at least one glass surface;
- b) treating the at least one glass surface with a silane formulation comprising at least one bis-silyl compound comprising at least one building block according to the following formula (A):
- wherein
- each Ra1 is independently selected from the group consisting of hydrogen, alkyl group, polyether group and aryl group,
- each Ra2 is independently an alkanediyl group,
- Ra3 is selected from the group consisting of hydrogen, alkyl group and aryl group,
- m is an integer ranging from 0 to 3,
- n is an integer ranging from 0 to 3;
- and
- c) treating the at least one glass surface with an additive formulation comprising at least one gliding agent selected from the group consisting of wax, fatty acid and fatty acid ester;
- such that the at least one treated glass surface is obtained.

- wherein the adhesion promotor comprises at least one bis-silyl compound comprising at least one building block according to the following formula (A);
- wherein
- each Ra1 is independently selected from the group consisting of hydrogen, alkyl:

5 more elements
A substrate comprising:
- i) at least one glass surface;
- ii) at least one silane based layer obtained by treating the at least one glass surface with a silane formulation, wherein the silane formulation comprises at least one bis-silyl compound comprising at least one building block according to the following formula (A):
- wherein
- each Ra1 is independently selected from the group consisting of hydrogen, alkyl group, polyether group and aryl group,
- each Ra is independently an alkanediyl group,
- Ra3 is selected from the group consisting of hydrogen, alkyl group and aryl group,
- m is an integer ranging from 0 to 3,
- n is an integer ranging from 0 to 3;
- and
- iii) at least one additive layer comprising the at least one gliding agent selected from the group consisting of wax, fatty acid and fatty acid ester on the silane based layer.
