The invention relates to a composition for producing abrasion-resistant and alkali-resistant layers or molded bodies having a low-energy surface, said composition comprising a) a hardenable binder system containing at least one organic polymer or oligomer comprising at least one functional group, or a precursor thereof, b) at least one fluorine-containing polymer or oligomer containing at least one functional group that can react with a functional group of the binder system, and c) inorganic particles, and to the products thus obtained. The coatings and molded bodies obtained are especially suitable for surfaces to be kept clean.

Abrasion-resistant and alkali-resistant coatings or moulded bodies having a low-energy surface

An article which comprises a surface of light metal. The surface is provided with an alkali-resistant protective coat comprising (a) an oxide layer which comprises silicon and boron as a basecoat and (b) an oxide layer which comprises silicon as a vitreous topcoat.

Alkali-resistant coating on light metal surfaces

A process for preparing a binder which comprises a heterocondensate of silicon compounds and metal and/or boron compounds. The process comprises mixing a silicon component which comprises (A), at least one hydrolyzable silicon compound having a non-hydrolyzable polymerizable group, with water to form a hydrolysis product, and 15 s to 15 min after mixing (A) with water, the addition of (B), at least one compound of boron or a metal selected from Al, Ga, In, Tl, Ge, Ga, Sn, Pb, Ti, Zr, Hf, Sc, Y and La.

Oil-, hot water-and heat-resistant binders, process for preparing them and their use

The invention relates to amphiphilic, nanoscalar particles comprising lipophilic hydrolyzable groups on their surface. The invention also relates to methods for producing amphiphilic, nanoscalar particles and to compositions containing said particles.

Amphiphilic nanoparticles

Substrates comprising a photocatalytic layer containing TiOare produced using TiOparticles which may optionally be doped with metallic or non-metallic elements or compounds. The photocatalytic layer exhibits a concentration gradient of the TiOparticles. An organically modified inorganic hybrid layer may be provided between the substrate and the photocatalytic layer.
