Abstract
The invention relates to a composition, its use and a method of its use as a glazing adhesive. The composition comprises an adhesive agent with thermoexpandable microcapsules which act as pressure actuators dispersed therein. The microcapsules are heat triggered so as to release at least one expandable volatile agent encapsulated within the microcapsule shell.
