The invention relates to a method for producing a solution comprising organofunctional siliconates, silicates and, optionally, the cocondensation products thereof, and to the solutions and an installation for the production thereof.

Solution comprising organofunctional alkali siliconates, silicates and method of production thereof

Low-VOC compositions of dialkyl-functional siloxane oligomers, especially of methylalkylalkoxysiloxanes, and processes for producing them are provided. Additionally methods for hydrophobizing porous mineral substrates employing the low-VOC compositions, in the course of which few or no volatile organic compounds are released, are provided.

Low-voc dialkyl-functional alkoxysiloxanes, processes and use thereof as hydrophobizing impregnating agents for mineral building materials

The invention relates to a composition and a method for the production of the composition comprising block cocondensates of propylfunctional alkaline siliconates and silicates.

Composition comprising block cocondensates of propylfunctional alkaline siliconates and silicates, and method for the production thereof

The present invention relates to a hydraulically setting mixture comprising: a) 6% to 25% by weight of cement, b) 50% to 90% by weight of at least one aggregate, and c) 0.01% to 8% by weight of at least one fluoroorganyl-substituted silicon compound, and also to materials produced from this mixture, more particularly components, concrete articles or mouldings. The invention further relates to the use of a hydraulically setting mixture of the invention for producing materials, more particularly components, concrete articles or mouldings, for example as facing concrete, where the surface of the materials exhibits only relatively low soiling tendency ('easy-to-clean' property) even on abrasion.

Cementitious mixture for materials having 'easy-to-clean' properties by modification of the unset material by means of fluorine-containing active ingredients

The present invention relates to a curable mixture suitable for obtaining 'easy-to-clean' properties in the cured mixture, comprising at least one mineral binder, a powder comprising at least one fluoroorganyl-substituted silicon compound encapsulated in a water-soluble polymer, the amount of the silicon compound being 0.001% to 8% by weight, based on the present mixture, and optionally further adjuvants, and also to a process for preparing the mixture and to the use thereof. The invention further relates to a water-redispersible powder and also to a corresponding intermediate for use in the curable mixture in order to obtain 'easy-to-clean' properties in the cured mixture. Also claimed, furthermore, is a process for preparing the powder, and the use thereof.
