1. A golf ball, comprising:
a core;
a cover disposed on the core; and
a coating disposed on the cover, wherein the coating is formed from a two-part reactive composition comprising hydroxyurethane linkages and urethane linkages, wherein the two-part reactive composition comprises a first part comprising a first reaction product of at least one cyclic carbonate and at least one amine-terminated component and a second part comprising an isocyanate-containing component.
2. The golf ball of claim 1 , wherein the amine-terminated component comprises a solvent.
3. The golf ball of claim 1 , wherein the cyclic carbonate comprises a five-membered cyclic carbonate, a six-membered cyclic carbonate, or a combination thereof.
4. The golf ball of claim 1 , wherein the amine-terminated component comprises two primary functional amines at terminal ends of a polyol backbone.
5. The golf ball of claim 4 , wherein the polyol backbone comprises a polyether polyol backbone.
6. The golf ball of claim 1 , wherein the amine-terminated component comprises three primary amine functional groups.
7. The golf ball of claim 1 , wherein the cyclic carbonate has a cyclocarbonate functionality of equal to or greater than 2.
8. The golf ball of claim 1 , wherein the isocyanate-containing component comprises a blocked isocyanate.
9. A golf ball, comprising:
a core;
a cover disposed on the core; and
a coating disposed on the cover, wherein the coating is formed from a two-part reactive composition comprising hydroxyurethane linkages and urea linkages, wherein the two-part reactive composition comprises a first part comprising a first reaction product of at least one cyclic carbonate and at least one amine-terminated component and a second part comprising an isocyanate-containing component.
