Method for adhering cured rubber components

A method for preparing a retreaded tire, the method comprising:

• a. providing a tire casing, where the tire casing includes natural rubber and styrene butadiene rubber;
• b. providing a pre-cured tire tread where the pre-cured tire tread includes natural rubber and styrene butadiene rubber;
• c. preparing a primer composition, where the primer composition includes
• (i) trichloroisocyanuric acid and water, or
• (ii) sodium dichloroisocyanurate and ethanol;
• d. applying multiple layers of the primer composition to the tire casing, the pre-cured tread, or both the tire casing and the pre-cured tread to thereby form a multilayer primer coating, where said step of applying includes
• (i) applying at least ten layers where the primer composition includes trichloroisocyanuric acid and water, or
• (ii) applying at least seven layers where the primer composition includes sodium dichloroisocyanurate and ethanol;
• e. applying a urethane-based adhesive composition to at least one of the tire casing, the pre-cured tread, and the multilayer primer coating to form an adhesive layer;
• f. 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
• g. allowing the adhesive layer of the pre-cured composite to cure and thereby form a retreaded tire, where said step of allowing the adhesive layer of the composite to cure takes place at a temperature of less than 80° C.
