Patent ID: 7427241

Claim:
A method for forming a golf ball component, which comprises: providing a first reactable component comprising an aliphatic isocyanate-containing compound and a second reactable component comprising at least one of a polyol, polyamine, or epoxy-containing compound, wherein the aliphatic isocyanate-containing compound comprises a reaction product of a polyamine, epoxy-containing compound, or a mixture thereof and at least one aliphatic polyisocyanate; combining the reactable components together to form a reactive mixture, wherein the reactive mixture has a gelation time, and wherein the first and second reactable components have a viscosity from about 25 cPs to about 5000 cPs at ambient temperature or at a temperature at which the reactable components are combined; injecting the reactive mixture into a golf ball mold having a desired shape within a first time that is less than the gelation time to avoid substantial solidification, and wherein the gelation time is about 1 second to about 10 seconds after combining; curing the reactive mixture to form a golf ball component within the gelation time; and removing the golf ball component from the golf ball mold.
