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.
