ABSTRACT:
The present invention is directed to aqueous polyurethane dispersions and aqueous polyurethane-acrylic dispersions, especially polymer dispersions formed from norbornane diisocyanate. The dispersions, and the dried polymers therefrom, are useful adhesives that provide enhanced bond strength when subjected to increased thermal and mechanical stress. Additionally, the inventive dispersions form polymers having increased adhesion compared to similar polymers based on cycloaliphatic diisocyanates which are free of a methylene bridge.
