The invention concerns a dispersion powder composition which is redispersible in water and is made from water-insoluble organic polymers, the composition being characterized in that it contains 0.1 to 30% by wt., relative to the weight of the organic polymers, of one or more silicon compounds which are dispersible in water and which have a boiling point at normal pressure of 160 degrees C., selected from the group comprising the silanes, polysilanes, oligosiloxanes, carbosilanes, polycarbosilanes, carbosiloxanes, polycarbosiloxanes and polysilylenedisiloxanes. The invention also concerns methods for manufacturing such compounds and their use.

Water-repellent plaster compositions comprising the constituents

Process for the water-repellent impregnation of plaster

Plaster is rendered water-repellent by impregnation with organosiloxanes containing Si-bonded hydrogen atoms and with alkali metal silicate. In particular, the water-repellent action is improved in the case of shaped plaster articles treated at high drying temperatures.

Organopolysiloxane-alkyltrialkoxysilane emulsions for impregnating

The invention relates to pollutant-resistant compositions containing organopolysiloxanes. They are used for producing impermeable walls and similar ground seals introduced into the earth. This pollutant-resistant organopolysiloxane-containing composition comprises (A) a salt of organic or inorganic acid and organopolysiloxane which has SiC-attached radicals containing basic nitrogen in amounts of at least 0.5% by weight of basic nitrogen, based on the weight of this organopolysiloxane, (B) organosilicon compound containing basic nitrogen in amounts of from 0 to 0.5% by weight, based on the weight of this organosilicon compound, (C) swellable clay minerals and (D) hydraulic binder.

Pollutant-resistant composition containing organopolysiloxanes

Organopolysiloxane compositions which comprise (A) a salt of a water-soluble organic or inorganic acid and an organopolysiloxane which has at least one SiC-bonded organic radical containing basic nitrogen, and (B) an alkoxylated alcohol and also, optionally, (C) a salt of a water-insoluble organic acid and an organopolysiloxane, which has at least one SiC-bonded organic radical containing basic nitrogen.

Organopolysiloxane composition

The invention relates to thermoinsulating moldings containing porous, inorganic thermoinsulating materials and having an organopolysiloxane coating thereon, in which an uncoated thermoinsulating molding is coated with a diorganopolysiloxane containing rod-shaped styrene-(meth)acrylate copolymers which are obtained from a free radical copolymerization of styrene and (meth)acrylate in the presence of the diorganopolysiloxane.

Thermoinsulating moldings containing a porous, inorganic

The present invention relates to a corrosion resistant coating for metal reinforcing structures that are used in porous concrete which comprises coating the metal reinforcing structures with an organopolysiloxane elastomer obtained by crosslinking a diorganopolysiloxane-based composition by the condensation reaction or by the addition of Si-bonded hydrogen to an aliphatic carbon-carbon double bond, in which the composition contains a copolymer that is obtained via a free radical copolymerization of styrene and a (meth)acrylic acid ester in the presence of the diorganopolysiloxane.
