The present invention relates to a method for producing a layer for coating the inner surface of a container and a glass or plastic container obtained by said method, wherein said container is suitable for containing products biocompatible with humans and/or animals. The method includes: forming a solution containing a solvent, water, a molecular precursor comprising alkoxy groups and an acid as a catalyst, - mixing said solution to initiate hydrolysis and condensation, - applying the resulting solution onto at least one portion of the inner surface of the container, while the solution is in the process of gelling, - the resulting applied solution is then dried at a temperature for a predetermined time, before curing. The acid is citric acid, and the invention is characterized in that said citric acid is at a concentration of less than 6 mol/l, and in that the solution comprises less than 1.5 units of precursor for each volume unit of acid. |
