Abstract: The present invention relates to a compound of the formula (I) for improving the tensile shear strength of hardened compositions based on silane-modified prepolymers, a composition containing a silane-functionalized prepolymer and a compound of the formula (I), a method for the production of this composition and the use of the compound of the formula (I) in adhesives, sealants, coatings and/or primers, based on silane-functionalized prepolymers and the use of this compound for the production of adhesives, sealants, coatings and/or primers based on silane-functionalized prepolymers.

Abstract: An application nozzle for viscous adhesives has a nozzle housing (1) encompassing an interior (4) that has an application edge (6) along which a plurality of nozzle openings (8, 33) are arranged, and has at least one feed opening (5) located opposite from the application edge (6). The interior (4) of the nozzle housing (1) widens from the feed opening (5) towards the nozzle openings (8, 33), as seen in the direction of the application edge (6). Flow elements (9, 10, 11) to convey the adhesive from the feed opening (5) to the nozzle openings (8, 33) are provided in the interior (4) of the nozzle housing (1) and at least one flow element (9, 10, 11) that has an inflow edge (12) and an outflow edge (13) and that is oriented in such a way that the flow element, while being completely surrounded by the volume flow of adhesive, uniformly distributes the volume flow of adhesive, taking into consideration the different flow paths leading from the feed opening (5) to the individual nozzle openings (8, 33).

Abstract: A sealing composition and method to seal building materials, especially cement-based floors, e.g., concrete, with such sealing composition is disclosed. The sealing composition can be used to seal fresh or wet building materials to reduce diffusion of water vapour through the set (hardened) sealing material. The sealing composition is a mixture based on moisture-curing silane functional polymers and monomers that may include hydrocarbon resins and other ingredients.
