  • Publication number: 20160031760
    Abstract: The use of a binder system comprising compounds containing aluminium oxide and silicon oxide for producing a hydrophilic building product, characterized in that the sum of the oxides calculated as Al2O3 and SiO2 in the binder system is ?40% by weight, based on the water-free binder system, and the contact angle of an oil drop placed on the surface of the cured building product is ?90°, where the contact angle determination is carried out under water, is proposed. The said hydrophilicity makes the building product easy to clean, with simple rinsing with water often being sufficient.

  • Patent number: 8785539
    Abstract: The present invention provides siliceous-based polyurea compositions, obtainable by reacting isocyanates, alkali silicates and hydratable aluminosilicates. Moreover, the present invention provides a process for the manufacture of these compositions, comprising the steps of mixing a hydratable aluminosilicate with an aqueous silicate and reacting this mixture with a polyisocyanate and/or a polyisocyanate prepolymer, optionally in the presence of a polyol and/or with the inclusion of an inert filler. Finally, the present invention provides the use of these compositions in the fields of aviation, automotive assemblies, construction, consumer products, fire protection, furniture components, insulation, shipbuilding and/or windmill construction. The compositions obtainable according to the present invention are lightweight, high load bearing, flame retarding materials.

  • Publication number: 20090318402
    Abstract: A ruthenium (II) compound of formula (I) wherein X is halo or a neutral or negatively charged O, N- or S-donor ligand; Y is a counterion; m is 0 or 1; q is 1, 2 or 3; A is either: (i) (Ru)—NRN1RN2—RN3—(N), where RN1 and RN2 are independently selected from H, optionally substituted C1-7alkyl, C3-20 heterocyclyl and C5-20aryl, and RN3 is C1-2alkylene; or (ii) a nitrogen-containing C5-6aromatic ring, wherein the nitrogen ring atom is bound to the ruthenium atom, and the ring is also bound to the azo-nitrogen, either by a single bond wherein the bond is ? or ? to the nitrogen ring atom, or by a —CH2? group wherein the bond is x to the nitrogen ring atom; B is optionally substituted C1-7alkyl, C3-20heterocyclyl or C5-20aryl.
