Sprayed polyurea covered golf ball
A golf ball with a cover formed by spraying is disclosed herein. In the present invention, a mixture of a low viscous diisocyanate component and a diamine free of organic solvent are sprayed onto a mantle insert to form a cover layer for a golf ball. A rapid reaction occurs and a solid layer forms within ten seconds. The polyurea material is extremely durable so that the cover layer performs with excellent shear cut durability.
1. A golf ball comprising:
a core;
a mantle layer having a surface comprising a plurality of dimples; and
a cover layer formed of a sprayed polyurea on the plurality of dimples of the surface of the mantle layer, the cover layer having a thickness ranging from 0.010 inch to 0.040 inch.
2. The golf ball according to claim 1 wherein the core is composed of a polybutadiene material, zinc penta chloride, organic peroxide, zinc stearate, zinc diacrylate and zinc oxide.
3. The golf ball according to claim 1 wherein the mantle layer is composed of a fully neutralized polymer material.
