Patent ID: 8261798

Claim:
A tire for a vehicle, comprising: an inner liner having an elastomer content that is in majority a butyl based rubber; a patch bonded to the inner liner, the patch having a bonding surface having an elastomer content that is in majority a diene rubber; a polyurethaneurea adhesive bonding the bonding surface of the patch to the inner liner, the polyurethaneurea adhesive is the reaction product of reaction components, the reaction components comprising: part A, wherein part A is a mixture comprising: between about 55 and about 75 wt. % of an oligomeric polyol having an average molecular weight greater than about 1000 wherein greater than 75 wt. % of the oligomeric polyols is primary oligomeric polyol; between about 3 and about 7 wt. % of an aromatic diamine chain extender; and between about 0.1 and about 1.5 wt. % of a reactivity catalyst; and part B, wherein part B is a mixture comprising: between about 1 and about 15 wt. % of a short aromatic diisocyanate; and between about 5 and about 35 wt. % of an aromatic diisocyanate prepolymer that is the reaction product of a short aromatic diisocyanate and a diol, wherein the mass fraction of each of the reaction components is based upon the total mass of the part A and part B reaction components.
