Abstract: The present invention relates to a one-component, moisture-curing foam consisting of 10 to 60% by volume of at least one gas and of a one-component, moisture-curing composition Z comprising at least one polymer P having isocycanate groups and/or alkoxysilane groups and 5 to 50% by weight of carbon black, based on the total weight of the one-component, moisture-curing foam. Such foams are suitable as adhesives or sealants, for the production of coatings or for the film-filling of hollow structures, in particular in vehicle construction.

Abstract: A dynamic mixer comprising a rotor, which is coupled to a drive shaft and which is rotationally mounted in a mixing chamber provided inside a rotor housing; at least one first and one second constituent can be fed to said mixing chamber; the drive shaft comprises at least one wavy channel via which the second constituent can be introduced into the mixing chamber; the mixing device is simplified since the second constituent is fed through the channel provided in the drive shaft; no separate connection for supplying the second constituent is provided on the rotor housing whereby enabling the rotor housing to have a simple design and be economically produced; the assembly and disassembly of parts are also simplified, particularly of the rotor and rotor housing, which can be disposed of or cleaned after the mixer has been used, allowing the dynamic mixer to be repeatedly reused.
