Pressurized Packaging Systems for One Component Adhesives and Sealants

Abstract

A pressurized container for dispensing a 1K adhesive or sealant composition is disclosed. The container has an outer container with at least one dispensing opening and a deformable inner container to be filled with the 1K composition. The inner container is accommodated in the outer container and also has a dispensing opening. The inner container is connected to the outer container. The outer container has a pressure generator containing an amount of activated carbon having a propellant gas adsorbed thereon.
