Abstract
Disclosed is a wallcovering assembly consisting of a base material and at least one ceramic coating/topcoat with or without an optional ceramic interlayer.
Claims8
A wallcovering assembly, comprising:
- a base material,
- at least one ceramic coating comprising ceramic particles selected from the group consisting of oxides of metals, oxides of semimetals, nitrides of metals, nitrides of semimetals, borides of metals, borides of semimetals, carbides of metals and carbides of semimetals embedded in a matrix consisting of a silicon network linked together by Si—O—Si bridges,
- and one or more ceramic interlayers present between the base material and the ceramic layer,
- wherein the ceramic interlayer contains particles of an inorganic component comprising essentially at least one component selected from the group consisting of at least one metal, at least one semimetal and at least one mixed metal with at least one element of the third to seventh main group that are bonded by at least one inorganic adhesive to each other and to the layer present underneath the ceramic interlayer, and
- wherein at least one of the ceramic coating and the ceramic interlayer comprise an inorganic-organic silicon network including an organic component covalently bonded between the Si atoms and wherein the organic component has a hydroxyl group and an amine group and a structural unit of the following formula (II):
- wherein R10 is an organic radical.
