ABSTRACT:
A two component, curable hot melt adhesive system includes a first hot melt adhesive formulation which has a softening temperature greater than room temperature and which includes a first component of a curable adhesive therein. The system includes a second hot melt adhesive formulation which has a softening temperature which is greater than room temperature and which includes a second component of a curable adhesive therein. The second component is reactive with the first component to provide a cured adhesive bond. In use, the two formulations are heated to a temperature above their softening temperature and are contacted so as to cause mixing. The mixture cools to provide a thermoplastic bond which subsequently cures to provide a permanent adhesive bond. While the first and the second component individually perform as hot melt adhesives, combining the first and the second gives enhanced adhesive performance in extended temperature ranges.
