<p>A composition and process for applying and adhering a cured elastomer tread to a cured elastomer article such as a tire at an ambient or a relatively low temperature. The tire is buffed, ground, and otherwise reduced to a suitable depth for the application of the tread thereto. An adhesive system includes a treating agent such as a N-halohydantoin, a N-haloamide, and N-haloimide, or a N-halosulfonamide, which is applied to the prepared tire surface. The adhesive system also includes an amine curable polymer or prepolymer containing an amine curing agent therein and an optional polar solvent is applied to the treated tire surface and to the elastomeric tire tread. The tire tread is then applied to the prepared tire and cured at a relatively low or ambient temperatures. Various additives can be added to the amine curable polymer or prepolymer and/or treating agent or to the tire and tread surface to improve adhesion of the tread to the tire carcass. The invention is suitable for passenger vehicle type tires, off-the-road type tires, and the like.</p> |
