A process has been described for producing a composition which can cure under the influence of moisture, in which the reactive end groups of a reactive polymer are reacted with a crosslinker to form the prepolymer, the process proceeding in batch and the production of the prepolymer takes place in a mixing vessel, characterized in that, after obtaining the prepolymer in the mixing vessel, the lid of the mixing vessel is lifted and the stirrer and / or scraper is retrieved from the liquid, the mixing vessel is sealed by means of two sheets of plastic film, wherein the first sheet is applied as well as possible against the product and against the upright wall of the opened mixing tub, and afterwards a second sheet is tensioned over the upper edge of the mixing tub. |
