ABSTRACT:
A golf ball having an improved urethane top coat is disclosed. The top coat is formed from a two-part polyurethane system where the first part contains a hydroxyl functional polyol and the second part contains a diisocyanate crosslinking agent selected from the group consisting of biurets of hexamethylene diisocyanate and isocyanurate trimers of hexamethylene diisocyanate. The top coat made with such crosslinking agents exhibits superior adhesion and abrasion resistance, and superior non-yellowing properties upon exposure to U.V. radiation.
