The present invention relates to foamable thermosetting polyurethane structural adhesive composites and compositions and processes for producing the same comprising dispersing a water-generating curing composition into a polyurethane base resin to form a nonactivated adhesive composite, and activating the same by heating to form an adhesive composition. Another aspect of the invention relates to dispersing a water-generating compound and an amine-terminated solid polyamide resin into the polyurethane base resin and heat-activating the same to form an adhesive composition. |
