Abstract
A process for coating at least a portion of a face of a siliceous substrate with a silicon containing layer, the process includes at least the following steps: a treatment step, in which at least the portion of the face of the siliceous substrate is treated with a composition containing at least one biocide, and at least the portion of the face of the siliceous substrate is reacted with a reactive composition for forming a silicon containing layer chemically bound to the siliceous substrate.
Claims27
A process for coating at least a portion of a face of a siliceous substrate with a silicon-containing layer, comprising the steps of:
- treating the portion with an aqueous composition including at least one biocide selected from the group consisting of:
- thiazole compounds and derivatives, isothiasole compounds and their derivatives, isothiazoline compounds and their derivatives, ammonium and its derivatives, phosphonium compounds and their derivatives, and ammonium-phosphonium compounds and their derivatives, and at least one free-radical scavenger selected from the group consisting of:
- 3,3-thiodipropionic acid, L-ascorbic acid, D-ascorbic acid, fumaric acid, diethylhydroxylamine, glutaraldehyde, butyraldehyde, L-tartaric acid, 4-methoxyphenol, propyl gallate and mixtures thereof, said aqueous composition including an amount of biocide sufficient for ensuring an activation of the portion;
- then
- treating the portion with a means for removing water present on the portion treated with the aqueous biocide containing composition, and then
- reacting the portion with a reactive composition, the reactive composition forming a silicon-containing layer chemically bound to the siliceous substrate.

- then
- washing the treated portion;
- then
- drying, at least partly, the washed portion, and then
- reacting the dried washed portion with a reactive composition for forming a silicon containing layer chemically bound to the siliceous substrate.
