Abstract: A fluid sensor for impedance-based determination of a quantity or a quality, such as type, composition, or purity of a fluid present in the surroundings of the fluid sensor, where the fluid sensor includes a first electrically conductive electrode which is arranged on a first extruded substrate component made of an electrically insulating, thermally curable synthetic, and where the fluid sensor includes a second electrically conductive electrode which is arranged on a second extruded substrate component made of an electrically insulating, thermally curable synthetic, where in each case an electrically conductive surface both that of the first electrode and also of the second electrode is exposed in such a way that it is wettable by fluid in the surroundings of the fluid sensor.

Abstract: A vehicle tank, in particular for holding a fuel, in particular gasoline and/or diesel fuel, having: a first and a second partial shell, wherein the first and second partial shell are connected to one another in a partial shell joining area, and a barrier layer substantially, preferably completely, covering an outer surface of the first partial shell and an outer surface of the second partial shell, respectively, wherein the barrier layer spans the partial shell joining area on an outer surface of the vehicle tank.

Abstract: Embodiments of the present disclosure include a thermoset cross-linked network and a method of producing the thermoset cross-linked network from a reaction product of a curable epoxy system in a liquid phase and cross-linked reactive polymer microparticles in a solid phase. For the various embodiments, the cross-linked reactive polymer microparticles have a cross-link density and reactive groups that covalently react with the curable epoxy system to provide the thermoset cross-linked network in a single contiguous phase having a topological heterogeneity.

Abstract: Embodiments of the present disclosure include a composition of cross-linked reactive polymer microparticles and a method of producing cross-linked reactive polymer microparticles that includes reacting an epoxy resin with an amine curing agent in a dispersing media at a temperature of 50° C. to 120° C. for a reaction time of no greater than 17 hours so that the cross-linked reactive polymer microparticles have no greater than 0.001 weight percent of the dispersing media bound to the cross-linked reactive polymer microparticles; and phase separating the cross-linked reactive polymer microparticles and the dispersing media.
