Abstract

A polyurethane coating for a golf ball that is based on polyol mixture containing acrylic polyol and BEPD based caprolcatone polyol is disclosed herein. The polyurethane coating comprises a part A component and a part B component, with the part A component comprising an acrylic polyol, a BEPD polyol, a 3-Oxazolidineethanol, a fluorosurfactant, a hindered amine light stabilizer, a UV-absorber, an optical brightener, a dibutyltin dilaurate catalyst, and an organic solvent, and the part B component comprising an aliphatic polyisocyanate and an organic solvent.

Claims (6)

1. A coating for a golf ball, the coating comprising:

a part A component comprising an acrylic polyol, a BEPD polyol, a 3-Oxazolidineethanol, a fluorosurfactant, a hindered amine light stabilizer, a UV-absorber, an optical brightener, a dibutyltin dilaurate catalyst, and an organic solvent; and

a part B component comprising an aliphatic polyisocyanate.

2. The coating according to claim 1 wherein the part B component further comprises an organic solvent.

3. The coating according to claim 1 wherein the aliphatic polyisocyanate is at least one of a HDI trimer, a HDI dimer, or a HDI biuret.

4. The coating according to claim 1 wherein the acrylic polyol ranges from 10% to 60% weight percent of the part A component, the BEPD polyol ranges from 10% to 60% weight percent of the part A component, the 3-Oxazolidineethanol ranges from 5% to 20% weight percent of the part A component, the fluorosurfactant ranges from 0.1% to 1.5% weight percent of the part A component, the hindered amine light stabilizer ranges from 0.1% to 3% weight percent of the part A component, the UV-absorber ranges from 0.1% to 3% weight percent of the part A component, the optical brightener ranges from 0.1% to 2% weight percent of the part A component, the dibutyltin dilaurate catalyst ranges from 0.1% to 3% weight percent of the part A component, the organic solvent ranges from 5% to 70% weight percent of the part A component, the aliphatic polyisocyanate ranges from 20% to 100% weight percent of the part B component, and the organic solvent ranges from 0% to 80% weight percent of the part B component.
