Beschreibung
Zusammenfassung:	A UV-curable coating (20) for use with golf balls (10) and other substances 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 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. Cette invention concerne un revêtement polymérisable aux UV (20) pour balles de golf (10) et autres produits comprenant un ou plusieurs polyéther acrylates à faible viscosité, une résine carbodiimide fonctionnelle, un ou plusieurs polyacrylates oligomères uréthanes aliphatiques à faible viscosité et un photoamorceur pris parmi un ou plusieurs mono-aryl kétones, triméthylbenzoyldiphényl phosphinates, et/ou phosphine oxydes. De plus, l'invention porte sur un procédé de polymérisation d'un revêtement polymérisable aux UV. Ce procédé consiste à pulvériser la composition sur l'extérieur d'un substrat dans un environnement de gaz inerte et à soumettre ce substrat à un rayonnement ultraviolet au moyen d'une lampe à vapeur de mercure dopée sous pression moyenne.
