Abstract
The present invention is a method for forming a golf ball, the method comprising mixing an aqueous polyurethane dispersion with an azridine to form an aqueous polyurethane dispersion/aziridine mixture. Then, adding the aqueous polyurethane dispersion/aziridine mixture to a water tank, to form a PUD/aziridine solution and dipping a polybutadiene core in the PUD/aziridine solution. The PUD/aziridine solution comprises 0.4 percent aziridine, 4 percent aqueous polyurethane dispersion, and 95.6 percent de-ionized water, which forms a dipped polybutadiene core. The dipped polybutadiene core is then dried at room temperature.
