ABSTRACT:
Improved sealants and adhesives derived from polyisocyanates having aromatically linked --NCO groups are cured at ambient temperatures when combined with a curing agent comprising an imino- and enamino-functional compound. These two component resin systems may be employed in fabricating multi-substrate laminates, especially those comprising lignocellulosic and cellulosic materials, such as wood and paper.
