20100144966 | Liquid oligomer composition containing hydroxyamine adducts and method of manufacturing thereof - Proposed is a liquid oligomer composition that contains a hydroxyamine adduct and a liquid reacting oligomer. The hydroxyamine adduct includes an epoxy-amine adduct, which contains at least one primary amine group that is a product of the reaction of an epoxy compound with at least one terminal oxyrane group and at least one amine that contains at least two primary amino groups. In order to form the epoxy-amine adduct, 1 to 15 moles of at least one amine are reacted per equivalent of the aforementioned epoxy compound. The composition also contains at least one compound with one or more terminal cyclocarbonate groups. A method of manufacturing a liquid oligomer composition on the basis of the above compounds is also proposed. | 06-10-2010 |
20100234497 | Nanostructured hybrid oligomer composition - A nanostructured hybrid liquid oligomer composition including at least one epoxy-functional component (A), at least one cyclic carbonate component (B), at least one amine-functional component (C), and, optionally, at least one acrylate (methacrylate) functional component (D), wherein at least one epoxy, amine, or acrylate (methacrylate) component contains alkoxysilane units. The composition is highly curable at low temperatures (approximately 10 to 30° C.) with forming of nanostructure under the influence of atmospheric moisture and the forming of active, specific hydroxyl groups by reaction of cyclic carbonates with amine functionalities. According to the present invention, the cured composition has excellent strength-stress properties, adhesion to a variety of substrates, appearance, and resistance to weathering, abrasion, and solvents. | 09-16-2010 |
20100319606 | CHEMICAL TAGGING INDICATORS AND METHOD TO LOCATE OVERHEATED SPOTS IN LIQUID-FILLED ELECTRICAL DEVICES - A method for identifying overheated spots in liquid-filled electrical devices, comprising the steps of: a) determining the locations of potentially overheatable spots in said device and mapping said locations; b) positioning a tag consisting of one or more chemical indicators on potentially overheatable spots in said devices, wherein when said tags are exposed to a given high temperature, they are depolymerized into thermal degradation products which are diffused into the liquid; c) identifying the thermal degradation products by analytical methods; and d) locating the overheated places according to the identified thermal degradation products and the map of locations of said tags; wherein the tags comprise polymers and copolymers, which are substantially absent from the liquid of the device at normal working conditions. | 12-23-2010 |
20120208967 | METHOD OF PRODUCING HYBRID POLYHYDROXYURETHANE NETWORK ON A BASE OF CARBONATED-EPOXIDIZED UNSATURATED FATTY ACID TRIGLYCERIDES - A method of obtaining hybrid polyhydroxyurethane compositions cross-linked at ambient temperatures. The method comprises: (a) reacting epoxidized unsaturated fatty acid triglycerides with carbon dioxide in the presence of a catalyst to obtain carbonated-epoxidized unsaturated fatty acid triglycerides, wherein conversion of oxyrane groups to 2-oxo-1,3-dioxolane groups (cyclic carbonate groups) for said carbonated-epoxidized unsaturated fatty acid triglycerides ranges from 35% to 85%; (b) mixing and reacting the carbonated-epoxidized unsaturated fatty acid triglycerides with a compound having amine functionality comprising at least one primary amine group realized at stoichiometric or within nearly balanced stoichiometry; (c) mixing and reacting the product of step (b) with a compound having amine functionality comprising at least two primary amine groups realized at excess of an amine-functional compound; (d) subsequently mixing the product of step (c) with a compound having amino-reactive groups. | 08-16-2012 |
