Abstract

A topcoat is applied to a surface of a golf ball using a carrier fluid comprising nitrogen gas or nitrogen-enriched air. The carrier fluid typically has air enriched to about 90-99.5% nitrogen. A mixture of carrier fluid and coating material may be sprayed onto the exterior of the golf ball. Nitrogen-enriched air delivery provides a number of benefits over compressed air delivery, such as reduced coating thickness, reduced variance in the coating thickness and average thickness, reduced pooling in dimple center, edge ratio closer to 1.0, faster cure times, reduced viscosity, less material usage, reduced material flow rate, reduced atomization air pressure, and decreased drying time.
