| 556414000 | The nitrogen is in an isocyanato or isothiocyanato group (i.e., -NCO or -NCS) | 10 |
| 20100004475 | PROCESS FOR PREPARING ISOCYANATOORGANOSILANES - The invention provides a process for preparing silanes which possess an isocyanate function, in which the silanes, after their chemical preparation, are purified and, after the purification, are handled exclusively in an atmosphere with a relative air humidity below 10%. | 01-07-2010 |
| 20100069656 | PROCESS FOR PREPARING ISOCYANATOORGANOSILANES - Isocyanate-functional silanes, particularly isocyanate-functional α-silanes, are prepared in good yield by a liquid phase thermolysis conducted in the presence of a catalyst at a pressure of >100 mbar, or >80 mbar when a thin-film evaporator is used. | 03-18-2010 |
| 20100286426 | METHOD FOR PRODUCING ISOCYANATE-TERMINATED SILOXANES - Isocyanate-functional or protected isocyanate-functional organopolysiloxanes are prepared directly by reaction of a siloxane bearing at least one silicon-bonded hydroxyl group with an alkoxy-functional α-silane containing an isocyanate group or blocked isocyanate group. | 11-11-2010 |
| 20120226063 | USE OF SALTS OF BRANCHED FATTY ACIDS AS CATALYSTS FOR CONVERTING STAR-SHAPED ALCOHOLS USING ISOCYANATES - The invention relates to the use of salts of branched fatty acids for catalyzing the reaction between star-shaped alcohols and isocyanates. | 09-06-2012 |
| 20120271063 | Surface Modifying Compositions - A surface modifying composition comprises an amphiphilic compound which is non-cellulose based, the amphiphilic compound including a covalently linked ionic moiety with the following formula: where M=metal oxide or binary metal oxide, Ai is selected from compounds with surface energy greater than or equal to 25 dynes cm | 10-25-2012 |
| 20130079538 | ALKOXYSILANE FUNCTIONALIZED ISOCYANATE BASED MATERIALS - Alkoxysilane functionalized isocyanate based materials of low viscosity prepared by reacting in any possible order of addition an organic polyisocyanate with an isocyanate-reactive compound and an amino-functional alkoxysilane of formula I | 03-28-2013 |
| 20130085290 | METHODS AND COMPOSITIONS FOR PREPARING SILICA AEROGELS - Cross-linked sol-gel like materials and cross-linked aerogels, as well as methods for making such cross-linked sol-gel like materials and cross-linked aerogels are described. | 04-04-2013 |
| 20150031906 | FLAME RETARDANT FILLER - A flame retardant filler having brominated silica particles, for example, imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In this example, brominated silica particles serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a flame retardant filler comprised of brominated silica particles. In an exemplary method of synthesizing the brominated silica particles, a monomer having a brominated aromatic functional group is reacted with functionalized silica particles (e.g., isocyanate, vinyl, amine, or epoxy functionalized silica particles). Alternatively, a monomer having a brominated aromatic functional group may be reacted with a silane to produce a brominated alkoxysilane monomer, which is then reacted with the surface of silica particles. | 01-29-2015 |
| 20150133682 | PREPARATION OF ISOCYANATO SILANES - A process for the preparation of alkoxysilyl group-containing isocyanate compounds which includes the step of reacting carbonyl chloride ClC(═O)Cl with an alkoxysilyl group-containing amine in the presence of a high boiling point base, and optionally in the presence of an inert organic solvent, in order to minimize by product production and to simplify product purification, is disclosed. | 05-14-2015 |
| 20160145275 | FLAME RETARDANT FILLER - A flame retardant filler having brominated silica particles, for example, imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In this example, brominated silica particles serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant.
