The invention concerns a method for producing a highly-porous ceramic layer and for application of this layer onto metallic, ceramic, enameled and/or glass substrates using porous, ceramic particles, preferably aluminum oxide, titanium oxide and zircon oxide, and an inorganic binder system. The inorganic binder system contains at least one ceramic nanoparticle of a particle size of less than 100 nm, preferably less than 50 nm and particularly preferred less than 25 nm, the solvent being water. Layers produced in this fashion are suited as self-cleaning catalytically active layers e.g. in ovens, in combustion engines etc. or for general coating of substances to considerably increase their specific surface e.g. for catalytic substrates.

Method for producing self-cleaning ceramic layers and a composition therefore

A composition containing transparent thermoplastic polymers and a surface modified oxide particles is disclosed. The size of the particles is less than 200 nm and the composition is suitable for the preparation of products wherever diathermancy is undesirable.

IR absorbing compositions

The present invention provides compositions containing transparent thermoplastic polymer, surface-modified oxide particles with a particle size of less than 200 nm, and organic NIR absorbers. The compositions of the present invention may find use in reducing diathermancy in sheets, films, glazing systems and roofing systems which may be incorporated into automobiles and buildings.
