Abstract

Disclosed is a one component, liquid, moisture curable polyurethane adhesive composition comprising the reaction products of a mixture including at least one polyol with an excess of one or more polyisocyanates and an acid component. In one embodiment some or all of the acid component is applied separately from the adhesive composition. The adhesive composition has enhanced bond strength to metals such as aluminum compared to currently available adhesives. The composition finds special use in panel lamination applications.
