A process for producing a coated lightweight metal substrate, in particular, an aluminium substrate, by a wet-chemical application of a coating composition to the lightweight metal substrate and thermally curing the coating composition is provided. A coating material composition is also described that is formed from a sol-gel material.

Alkali-resistant coating for lightweight metals, in particular aluminum

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

Disclosed is a process of preparing a moulded article, comprising 1) hydrolyzing a) at least one silane having one non-hydrolysable organic group, and b) at least one compound selected from b1) a silane having two non-hydrolysable organic groups, and b2) a hydrolysable polysiloxane, or a mixture thereof, and c) optionally at least one silane having no non-hydrolysable organic group, to prepare a composite composition comprising a hydrolysate or condensate, 2) placing the composite composition in a mould, 3) curing the composite composition to increase the degree of condensation, 4) removing the moulded article from the mould, and 5) heat treating the moulded article at a temperature of at least 100&#xb0; C. The moulded article is preferably an optical lens which may be used for automobile headlights.

Siloxane composite-based light-weight optical lenses

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

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.

A process for preparing a composition for producing nanostructured mouldings and layers comprises contacting an aqueous and/or alcoholic sol of a compound of an element selected from silicon sand metals of the main groups and transition groups of the Periodic Table with species possessing hydrolysable alkoxy groups and comprising at least one organically modified alkoxysilane or a precondensate derived therefrom, under conditions which lead to (further) hydrolysis of the species, and subsequent removal of the alcohol formed and any alcohol already present originally. The process is characterized in that the alcohol is removed in an amount such that the residual alcohol content of the composition is not more than 20% by weight.
