Abstract:
Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. These waterproof gypsum panels have many uses, such as, tile backer board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, interior wall and ceiling, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, preferably silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives. Preferably a pre-coated non-woven glass fiber mat is employed to provide the inorganic mineral fibers for the surface reinforcement.

Abstract:
The invention relates to a preparation for chemical treatment of glass, ceramic and stone surfaces consisting of esters of fatty acids, monomeric organo-silicon compounds and organic solvents. Glass, ceramic and stone surfaces treated with the invention show excellent hydrophobicity and shine. Furthermore, the application of the invention prevents damages of the treated surfaces caused by abrasion during transport, abiding of fingerprints on the treated surfaces and dust accumulation on the treated surfaces.
Abstract:
Material treatment compositions for various materials and methods of treating the same is disclosed. A material treatment composition includes at least one silane-containing material, at least one base-containing material, and at least one solvent to enhance the strength of a material contacted by the composition.
Abstract:
Die Erfindung betrifft eine Verwendung einer Zusammensetzung enthaltend Polyorganosiloxan S und ein Verfahren zur Verminderung von Korrosion an Stahlarmierungen in Stahlbetonkonstruktionen, sowie ein Betonwerk, das unter Einsatz solcher Zusammensetzungen hergestellt wird. Es ist hervorragend geeignet für die Sanierung von Altbeton aber auch für die Korrosionsionhibierung von Armierungseisen in Frischbeton.
Abstract:
A protective surface modification system employs two separate formulations to enhance visual appearance and in many instances provide abrasion resistance on a surface such as a countertop.

Verwendung von Hydrophobinen zur Behandlung der Oberfläche von gehärteten mineralischen Baustoffen, Naturstein, Kunststein oder Keramik, Verfahren zur Behandlung derartiger Oberflächen sowie Oberflächen von gehärteten mineralischen Baustoffen, Naturstein, Kunststein oder Keramik, welche eine Hydrophobine umfassende Beschichtung aufweisen.
Abstract:
Shaped, preferably porous, inorganic bodies are provided which are prepared from a reactive blend. In accordance with one preferred embodiment, the solution is absorbed into a porous sacrificial substrate such as a cellulose sponge. The solution-saturated substrate is heated and an oxidation-reduction reaction occurs thereby forming an inorganic solid. A shaped, inorganic body is formed in situ. Optional, but preferred additional thermal treatment of the shaped, inorganic body removes the organic substrate, leaving an inorganic body that faithfully mimics the porosity, shape, and other physical characteristics of the organic substrate. Inorganic substrates may also be used to good effect. Large varieties of shaped bodies can be prepared in accordance with other embodiments of the invention and such shapes find wide use in surgery, laboratory and industrial processes and otherwise. The invention also provides chemically and morphologically uniform powders, including those having iniformly small sizes.
