Abstract

Golf balls typically utilize two part polyurethane coatings due to the abrasion resistance, adhesion and weatherability. The isocyanate portion of these materials was historically a toluene diisocyanate (TDI) prepolymer. However, with the advent of high whiteness golf balls, it is important that the coating for the golf balls maintains its water white appearance, along with maintaining all of the other properties (adhesion, abrasion resistance, gloss retention, etc.). It is also important to decrease the amount of volatile organic carbon (VOC) that evaporates from the coating during the spraying and curing of the golf ball coating.

Keywords: Golf balls, Polyurethane, Biuret, Trimer, Ultraviolet.


1 Introduction

The golf ball has under gone a great deal of metamorphosis over the past 100 years. One aspect that has changed dramatically are golf ball coatings, the thin layers of material that are the outer surface of the golf ball.

In the past, the golf ball was finished with up to five layers of coating. These consisted of an epoxy primer, two layers of a titanium dioxide (TiO2) containing white paint, and two layers of a clear top coat. This process required a great deal of handling and resulted in a large amount of organic solvent emission from the finishing process.

The golf ball that is manufacture today has a much simplified coating process. A water borne primer is applied to the golf ball as a tie layer between the ionomer cover and the clear top coat. The golf ball logo is then applied on to the primer. The final step is the application of a solvent borne polyurethane clear coat. This final clear coat contains small amounts of additives to enhance the coatings performance. One such additive that may be utilized is a narrow range u.v. absorber. This paper will describe in depth the chemical nature of the solvent borne polyurethane top coat and one of the enhancing additives, a narrow range u.v. absorber.
