ABSTRACT:
A golf ball is disclosued, comprising: a core, the core having a diameter of 1.5 inches to 1.65 inches and a first coefficient of restitution of 0.8 or greater at 125 ft/s; an intermediate layer disposed about the core, the intermediate layer having a first Shore D hardness of 20 to 80 and comprising a blend of two or more ionomers; and an outer cover layer disposed about the intermediate layer; the outer cover layer having a thickness of 0.005 inches to 0.05 inches and a second Shore D hardness of 30 to 70, the outer cover layer being composed of a castable material formed from reactants comprising at least one fluorinated polyfunctional compound, wherein the golf ball has a second coefficient of restitution of 0.8 or greater at 125 ft/s and a compression of 50 to 120.
