Abstract
A metering and application system for a moisture-curing polymer material includes a reservoir for the polymer material and a first pump and a second pump, wherein the polymer material is conveyable by the first pump from the reservoir to the second pump. In addition, a gas metering device with a defined pressure ratio is provided to bring a gas to a defined pressure, wherein the gas metering device is connected to the input of the second pump on its outlet side. In addition, a mixer for mixing the polymer material and the gas and a valve arranged downstream of the mixer for metering and a nozzle for applying the polymer material/gas mixture are provided.
