PRODUCTION OF MOISTURE-SENSITIVE PRODUCTS WITH PRESSURE CHANGES

Production of moisture-sensitive products with pressure changes Described is a method for the production of a moisture curable composition, using a mixing vessel for the production of the prepolymer by the reaction of a reactive polymer with a cross-linking agent, whereby after the introduction of a...

Zusammenfassung:	Production of moisture-sensitive products with pressure changes Described is a method for the production of a moisture curable composition, using a mixing vessel for the production of the prepolymer by the reaction of a reactive polymer with a cross-linking agent, whereby after the introduction of at least one liquid reagent for the reaction or another liquid ingredient of the formulation, the content of the mixing vessel is stirred and the closed mixing vessel is put under a vacuum pressure, whereby the vacuum pressure is preferably at most 0.50 bar absolute (bara), and optionally at least. 0.001 bara or 1 mbar absolute, whereby this vacuum pressure is broken by letting dried air into the mixing vessel.
