Abstract
The present invention relates to thermosetting polyurethane structural adhesive composites and compositions and processes for producing the same comprising dispersing an amine-terminated solid polyamide resin 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 an amine-terminated solid polyamide resin and a water generating compound into the polyurethane base resin and heat-activating the same to form an adhesive composition. The invention also relates to polyurethane base resins suitable for use in the processes of the invention, which may also be moisture cured to form a reactive adhesive composition.
