Abstract
A pressure-sensitive structural adhesive is formed by applying a thin layer of pressure-sensitive adhesive to one or both sides of a core layer of partially cured structural adhesive. The pressure-sensitive adhesive provides a tacky surface allowing a temporary bond at room temperature. Upon curing of the construction, the bond properties change to that of a structural adhesive, providing a strong permanent bond. Upon cure, the skin layer or layers of pressure-sensitive adhesive are absorbed into the layer of structural adhesive.
