Abstract
Golf equipment having improved cut and shear resistance that includes a polyurea composition, preferably saturated and/or water resistant, formed of a polyurea prepolymer and a curing agent, wherein the polyurea prepolymer includes an isocyanate and an amine-terminated compound, and wherein the curing agent includes a hydroxy-terminated curing agent, amine-terminated curing agent, or a mixture thereof.
Claims18
A golf ball comprising a core and a cover, wherein at least one layer comprises a composition comprising:
- a polyurea prepolymer comprising a reaction product of an isocyanate and an amine-terminated component, wherein the amine-terminated component is selected from the group consisting of
- wherein x is at least 1, n is from about 1 to 12, and R comprises an alkyl group having from 1 to 20 carbon atoms, a phenyl group, a cyclic group, or a mixture thereof;
- and
- a curative.
A golf ball comprising a core, an inner cover layer, and an outer cover layer, wherein the outer cover layer is formed of a composition comprising:
- a prepolymer, wherein the prepolymer comprises an isocyanate and an amine-terminated component, wherein the amine-terminated component is selected from the group consisting of
- wherein x is at least 1, n is from about 1 to 12, and R comprises an alkyl group having from 1 to 20 carbon atoms, a phenyl group, a cyclic group, or a mixture thereof;
- and
- an amine-terminated curing agent.
A golf ball comprising a core and a cover, wherein at least one layer comprises a composition comprising:
- a polyurea prepolymer comprising a reaction product of an aliphatic isocyanate and an aliphatic amine-terminated hydrocarbon;
- and
- an aliphatic curing agent.
