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.
