Abstract: The present invention provides compositions comprising at least one reaction product obtained from a reaction mixture comprising i) at least one mercaptosilane MS, and also ii) at least one polysilane PS which contains in particular at least one secondary or tertiary amino group, preferably a secondary amino group, and also iii) at least one epoxy resin EP. The compositions are suitable as adhesion promoters, more particularly in the form of primers. They exhibit good adhesion and are especially suitable for the adhesive bonding of glass and glass ceramic.

Abstract: The invention relates to a sealing arrangement composed of at least: two adjoining structural parts (2) made of concrete, steel, reinforced concrete, cast iron or other materials, and a sealing profile (8) which is made of polymer material and sealingly bridges the gap (4) between the two structural parts (2). The sealing arrangement according to the invention is characterized in that: the sealing profile (8) is composed of two or more co-extruded sealing parts (A1, B1) that form an adhesive join, the sealing parts being produced using at least two different types of polymer materials that are distinguished by having common elastic properties but having different mechanical and/or chemical and/or biological properties. Advantageous co-extruded sealing part constructions and material combinations are proposed.

Abstract: The present invention relates to a one-component polyurethane composition comprising at least one polyurethane prepolymer having terminal isocyanate groups which is prepared from at least one polyisocyanate and at least one polyol, and to at least one catalyst system which is obtainable from at least one bismuth compound and at least one aromatic nitrogen compound. The invention additionally relates to a use of this polyurethane composition as an adhesive, sealant, coating or lining. Finally, catalysts for polyurethane compositions are disclosed which represent coordination compounds between bismuth and at least one aromatic nitrogen compound.

Abstract: A method and a device for the continuous, single-step production of a homogenous solution of cellulose in hydrous aminoxides on the basis of cellulose and aqueous aminooxides, preferably N-methylmorpholino-N-oxide (NMMO), at temperatures in the range of from 50 to 130° C. under a vacuum and water evaporation. The cellulose and the NMMO are dosed separately to the device, mixed while sheared, the water is evaporated until the mixture is dissolved, the solution is homogenized and directly fed to the consumer via screw conveyors, pumps and filters.
