Abstract: A stirring element device, in particular for mixing media with a wide range of viscosities, in particular for a polycondensation reactor, includes at least one inner stirring blade and at least one outer stirring blade which are rotatable about a common axis of rotation, wherein at least the inner stirring blade is inclined at least section-wise relative to the axis of rotation. The inner stirring blade is arranged entirely in a subregion around the axis of rotation which is equivalent to a cylinder sector with a circular sector of less than 360° as base area.

Abstract: The present invention relates to a process for producing nanocapsules employable as thermo latent polymerization catalysts, in particular for the polymerization of polyurethanes, by means of a high shear process, wherein the process comprises: (i) emulsifying a first reaction mixture (a) in a continuous aqueous phase comprising at least one stabilizer; (ii) emulsifying a second reaction mixture (b) in a continuous aqueous phase comprising at least one stabilizer; (iii) combining the first reaction to the nanocapsules produced by means of the described processes, to the use thereof, and to agents which contain these nanocapsules.

Abstract: The invention relates to a one-component structural adhesive having a flow limit of at least 1500 Pa and an initial adhesion of more than 30 g/cm2, which contains at least one thickening agent and/or at least one filler. The invention further relates to the manufacture of such one-component structural adhesives and to the use of one or more thickening agents and/or one or more fillers for the manufacture of solid to kneadable one-component structural adhesive compounds having high initial adhesion.

Abstract: Two-component assembly adhesives with high early tack, with component A containing 0.5 to 50% of polysaccharides, water, and water-soluble salt, and component B containing water, water-soluble salt, and polysaccharides, the adhesive also containing a water-soluble, water-dispersible polymer.

Abstract: Polymer dispersions containing water, at least one water-dispersible polymer, and at least two ions or elements selected from the group consisting of Li, Ba, Sr, B, Co, Cu, Mn, Mo, Ni, Ag, Pb, Zn, W, La, Ce and Sn or salts thereof. The ions or elements are present in the dispersion in amounts of at least 10 ppm.

Abstract: The present disclosure provides a silane crosslinking adhesive, sealant or coating containing a polymer, consisting of an organic framework that supports at least two alkoxy or acyloxysilyl groups and at least one filler. The filler consists at least partially of a highly disperse silicic acid with a BET surface area of 35 to 65 m2/g and is present in the adhesive, sealant or coating in a quantity of 1 to 60% by weight, in relation to the total weight of said adhesive, sealant or coating. The disclosure also provides the use of the adhesive, sealant or coating for bonding plastics, metal, glass, ceramics, wood or wood-based material, paper, paper-based material, rubber and textiles.

Abstract: Gap-filling cyanoacrylate adhesives containing cyanoacrylate esters and organic halogenated polymers with a K-value of at least 46.

Abstract: Adhesive compositions containing less that 15% by weight of a binder containing a silyl-substituted polyurethane and more than 20% to 95% by weight of a filler. The compositions are useful for bonding object surfaces to inert substrate surfaces and are detachable with little to no substrate surface damage.

Abstract: Solutions of non-functional thermoplastic polymers in preferably high-boiling dissolving agents/plasticizers are suitable as additive additions in high-strength adhesives/sealant comprising high percentages of carbon black as a reinforcing filler for windscreen glazing in automobile construction for increasing the electrical resistance and thus for improving the electrical properties of antennae integrated into the vehicle windscreens.

Abstract: A device for expressing free-flowing compositions is presented having a cylindrical container (1) for accommodating a free-flowing component (2), two axially displaceable pistons (3) and (4) designed to close the cylindrical container, and a material outlet opening (5) at the lower end of the cylinder wall. The material outlet opening only releases the flow of the component (2) after the piston (4) has been moved past the material outlet opening into the end position (4′) by the expressing pressure. The device can be used with a conventional applicator for one-component adhesives, sealants or coating materials to provide the addition of a second component.
