Methods for producing polymer-containing coatings upon cured inner liners, methods for producing tires containing such inner liners, and tires containing such inner liners

A method for producing a tire comprising a cured inner liner and at least one component positioned radially inward of the cured inner liner, the method comprising:

• a. providing a tire body comprising a cured inner liner comprising rubber, a majority of which comprises butyl rubber, optionally halogenated, wherein the cured inner liner comprises an upper surface and a lower surface which is radially inward-facing within the tire body and wherein the lower surface of the cured inner liner comprises a release treatment comprising polysiloxane moieties;
• b. treating the lower surface of the cured inner liner with a coating composition comprising
• i. a silyl-terminated polymer in an amount of 40 to about 75% by weight, based upon the total weight of the coating composition used to treat the lower surface of the inner liner,
• ii. optionally at least one plasticizer,
• iii. at least one tackifier,
• iv. at least one adhesion promoter,
• v. optionally at least one moisture scavenger,
• vi. at least one catalyst,
• vii. optionally at least one antioxidant, and
• viii. no more than 10% by weight of filler, based upon the total weight of the coating composition used to treat the lower surface of the inner liner,
• thereby forming a polymer-containing coating upon the radially inward-facing surface of the cured inner liner;
• and
• c. providing a tire component and adhering the component to the polymer-containing coating upon the radially inward-facing surface of the cured inner liner.

A cured tire comprising a tire body, a cured inner liner, and at least one component positioned radially inward of the cured inner liner,

• the cured inner liner comprising rubber, a majority of which comprises butyl rubber, optionally halogenated,
• wherein the cured inner liner has an upper surface and a lower surface with the lower surface positioned radially inward within the tire and,
• the lower surface of the cured inner liner includes a polymer-containing coating comprising
• i. a silyl-terminated polymer in an amount of 40 to about 75% by weight, based upon the total weight of the polymer-containing coating composition,
• ii. optionally at least one plasticizer,
• iii. at least one tackifier,
• iv. at least one adhesion promoter,
• v. optionally at least one moisture scavenger,
• vi. at least one catalyst,
• vii. optionally at least one antioxidant, and
• viii. no more than 10% by weight of filler, based upon the total weight of the polymer-containing coating,
• the polymer-containing coating has a thickness of about 10 to about 1000 micrometers, and
• the at least one component positioned radially inward of the cured inner liner is adhered to the polymer-containing coating of the lower surface of the cured inner liner.
