Production of a hydrophobic surface on silicate ceramic objects comprises application of an intermediate layer to produce a porous surface and a layer having ultraphobic and/or hydrophobic properties

摘要

A process for the production of a hydrophobic or ultraphobic surface on objects prepared from silicate ceramic comprises (A) application of an intermediate layer to produce a capillary-porous surface (B) application of a layer having ultraphobic and/or hydrophobic properties. An independent claim is included for the hydrophobically and/or ultraphobically treated object.
