A thermosettable adhesive is used to secure a laminate having a compliant layer (for example, a foamable composition containing a diene rubber), a layer comprised of a thermosettable resin capable of being cured to a rigid state, and an optional carrier layer (for example, a metal foil) to a substrate for the purpose of strengthening, stiffening, or otherwise reinforcing the substrate. The substrate may, for example, be a metal vehicle door. The thermosettable adhesive is comprised of at least one polyol such as a polyether polyol, at least one epoxy resin, and at least one polyisocyanate.
