Estimating the term…
The invention relates to a method for producing a hybrid organo-mineral layer (12) for coating the inner surface (13) of a receptacle as well as to said receptacle for holding products that are biocompatible for humans and/or animals. According to the invention, a solution is formed that contains at least one solvent, water, at least one complexing molecular alkoxysilane precursor, at least one organo-functional molecular precursor and/or silicone, and a catalytic acid, the complexed solution, which is undergoing hydrolysis and condensation, is applied to at least one portion of the inner surface of the receptacle, the applied solution is dried at a specific temperature, and the receptacle is conveyed away and stored.
A process for the manufacture of a neutral hybrid organo-inorganic barrier layer (12) for coating the internal face (13) of a receptacle (15) suitable for containing products biocompatible with man and/or animals, in which:
A receptacle (15) suitable for containing products biocompatible with man and/or animals, comprising an internal surface (13), characterized in that said internal surface is covered, over at least a part, with a solidified sol-gel coating layer (12) obtained from a solution containing at least one solvent, water, at least one first complexing molecular precursor of the family of the alkoxysilanes, at least one second organofunctional molecular precursor and/or silicone, and citric acid as catalyst, said coating forming a hybrid organo-inorganic matrix arranged in order to produce at least one chemical barrier.
