  • Publication number: 20230202129
    Abstract: A method for preparing a retreaded tire, the method comprising (a) providing a tire casing; (b) providing a pre-cured tire tread; (c) applying a primer composition to the tire casing, the pre-cured tread, or both the tire casing and the pre-cured tread therefore form at least one primer layer, where the primer composition includes a halogenating agent and a solvent; (d) applying a urethane-based adhesive composition to at least one of the tire casing, an adhesive layer, the pre-cured tread, or the at least one primer layer; (e) mating the pre-cured tread to the tire casing to thereby sandwich the adhesive layer between the pre-cured tread and the tire casing and form a pre-cured composite: and (f) allowing the adhesive layer of the pre-cured composite to cure and thereby form a retreaded tire.
