Abstract

A golf ball having a soft outer surface coating having a hardness less than about HB on the ASTM D3363 scale, or less than about 40 on ASTM D2134 scale. The soft outer surface coating may contain polyurethane, a hydroxyl functional silicone material, or a hydroxyl functional fluoro material. Also, a method for making the golf ball. The golf ball having the soft outer surface coating exhibits a high spin rate over short shots essentially without degrading performance on driver shots, as compared with the performance of the uncoated golf ball.

Claims (6)

1. A golf ball comprising an outer surface coating incorporating a low surface energy composition and having a hardness either (a) 2B on the ASTM D3363 scale or (b) less than about 35 on ASTM D2134 scale, wherein the outer surface coating has a surface energy less than about 40 dynes/cm.

2. The golf ball of claim 1 , wherein the soft outer surface coating comprises polyurea.

3. The golf ball of claim 1 , wherein the low energy composition comprises a member selected from the group consisting of hydroxyl-functional fluoropolymer, amine-functional fluoropolymer, hydroxyl-functional silicone, amine-functional silicone, and combinations thereof.

4. A golf ball comprising an outer surface coating incorporating a low surface energy composition to provide the outer surface coating with a surface energy less than about 40 dynes/cm and having a hardness either (a) 2B on the ASTM D3363 scale or (b) less than about 35 on ASTM D2134 scale, and wherein the golf ball exhibits a high spin rate over short shots essentially without degrading performance on driver shots, as compared with the performance of the uncoated golf ball.

5. The golf ball of claim 4 , wherein the soft outer surface coating comprises polyurea.

6. The golf ball of claim 4 , wherein the low energy composition comprises a member selected from the group consisting of hydroxyl-functional silicone, amine-functional silicone, hydroxyl-functional fluoropolymer, amine-functional fluoropolymer, and combinations thereof.
