Abstract:
1. A process for making a product with a long-lasting, easily-cleaned surface by coating the surface with a hydrophobic and/or dirt-repellent material to form a coating on the surface, said coating having properties that are homogeneous or uniform in cross section through said coating, wherein said process comprises the steps of: a) applying a coating mixture to said surface so as to form a gel network having a backbone on said surface, said coating mixture comprising a hydrolyzable, network-forming gel and a hydrophobic and/or dirt-repellent substance; and b) chemically binding the hydrophobic and/or dirt-repellent substance in the backbone of the gel network on said surfaces; wherein the coating consists of said gel network with said hydrophobic and/or dirt-repellant substance bound in the backbone of the gel network so that said hydrophobic and/or dirt-repellant substance is distributed in a uniform concentration throughout said coating.
