ABSTRACT:
A UV-curable coating for use with golf balls and other substrates includes one or more low viscosity polyether acrylate, a functional carbodiimide resin, one or more low viscosity aliphatic urethane polyacrylate oligomer, and a photoinitiator selected from one or more of S mono-aryl ketones, trimethylbenzoyldiphenyl phosphinates, and/or phosphine oxides. In addition, a method of curing a UV-curable coating is disclosed. The method includes the steps of spraying the formulation onto the exterior of a substrate, surrounding the substrate in an inert gas environment, and irradiating the substrate with ultraviolet radiation from a doped medium pressure mercury vapor lamp.
