Polyurethaneurea system

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.
