Abstract
A container is provided that includes a container body with an outer surface and an inner surface. The inner surface contains silicon oxide and the silicon oxide containing inner surface is at least partially modified with a fluorine containing compound. The fluorine containing compound is chemically bonded to the silicon oxide of the container body via at least one Si—O—Si bond.
Claims28
A method for producing a container of low particulate emission, comprising the steps of:
- providing a container body having an outer surface and an inner surface, the inner surface comprising silicon oxide;
- applying a mixture of an organic fluorine compound dissolved in a solvent to at least a portion of the inner surface;
- and
- drying the fluorine containing compound and crosslinking the fluorine containing compound with the silicon oxide at the inner surface by a condensation reaction.
A method for producing a container with low particulate emission, comprising the steps of:
- providing a container body having an outer surface and an inner surface, wherein the inner surface contains silicon oxide;
- applying a mixture of an organic fluorine compound dissolved in a solvent to at least a portion of the inner surface of the container body, wherein the fluorine containing compound is an alkoxysilane compound, wherein said alkoxysilane compound has a structure as follows:
- wherein the linker comprises at least one hydrolyzable group, and/or an amino group, and/or a carboxamide group —OC—NH—, and/or at least one further silane group, and/or an acrylate or methacrylate group, and
- wherein ORe represents an alkoxy group, and wherein the backbone comprises a fluorine containing entity;
- drying the fluorine containing compound and crosslinking the fluorine containing compound with the silicon oxide at the inner surface of the container body by a condensation reaction;
- and
- crosslinking the fluorine containing compounds with each other via the linker.
