20110308730 | 2-ETHYLHEXYL METHYL TEREPHTHALATE AS PLASTICIZER IN ADHESIVES AND SEALANTS - The invention provides an adhesive or sealant comprising (A) at least one compound selected from the group consisting of polyurethanes, polyureas, polyacrylates, polysulphides, silylated polyurethanes, silylated polyureas, silylated polyethers, silylated polysulphides and silyl-terminated acrylates, and (B) at least 0.32% by weight of 2-ethylhexyl methyl terephthalate, based on the overall adhesive or sealant. A process is disclosed for preparing the adhesive or sealant, and also disclosed is the use thereof for producing material bonds between parts to be joined. | 12-22-2011 |
20110309533 | Rotating surfaces for SDR - The proposed spinning disc reactor comprises substantially a horizontally rotatable, disc-like and thermostatable support element which has an outer reaction surface, feed means for feeding at least one reactant onto the reaction surface and internal structures for thermostating the reaction surface. In addition, it contains at least one separation apparatus for collecting and removing the reaction product from the reaction surface. The support element is characterized in particular in that it consists of two components a) and b) arranged horizontally one on top of the other and having substantially identical surface measures. These two components are connected to one another in an interlocking manner and tightly during the operating time and the lower component a) has, on its top facing the inner region of the support element, at least one substantially uninterrupted groove milled in over an extensive area and intended for receiving, conducting and discharging a heat-transfer fluid. In addition, it has at least two bores for feeding and discharging the heat-transfer fluid, at least one profiled seal encircling the outer surface region being arranged between the component a) and the component b). The two components a) and b) as a whole are reversibly connected to one another. As a result of such specific features, a simply designed reactor which is advantageous with respect to maintenance, is versatile and permits targeted control of the chemical reaction on its rotating surface is present. | 12-22-2011 |
20130303804 | Process For Preparing A Thixotroping Agent And Use Thereof - The invention provides a process for preparing a thixotropic agent based on a urea derivative, in which the components α) comprising at least one amine and β) comprising at least one isocyanate, are supplied separately to a mixing means and are mixed with one another, the reaction mixture being discharged by spraying or squirting from the mixing means. Further disclosed is the use of the thixotropic agent in a fluid system. The process is especially suitable for preparing adhesives and sealants. | 11-14-2013 |
