Abstract
Unique insulation articles including corrosion inhibitors and methods of producing the same are disclosed. One exemplary embodiment is an article of manufacture comprising an insulation mat comprising a cured combination of a plurality of randomly oriented fibers and a binder, the insulation mat extending between a first surface and a second surface, a veil attached to the first surface, the veil structured to inhibit physical movement of the cured combination through the veil, a metal sheet attached to the second surface by a water-containing adhesive contacting the metal sheet and the second surface, and a corrosion inhibitor composition deposited on the cured combination of the insulation mat, the corrosion inhibitor composition being effective to modify toward neutral a pH of the cured combination in contact with water from the water-containing adhesive.
