Abstract

A method of casting a portion of a golf ball comprising the steps of providing a single component that is blocked and stable at a first predetermined temperature and becomes unblocked at a second predetermined temperature, wherein said second predetermined temperature is higher than the first predetermined temperature; and reacting said single component at the second predetermined temperature to form the surrounding layer.

Claims

1. A method of casting a portion of a golf ball comprising the steps of:

providing a single component comprising a uretoione that is blocked and stable at a first predetermined temperature and becomes unblocked at a second predetermined temperature, wherein said second predetermined temperature is higher than the first predetermined temperature;

grinding uretdione;

dispersing the ground uretdione in a liquid of polyol or polyamine;

combining with at least one catalyst to create a slurry;

pouring the slurry into a mold and heating the mold to the second predetermined temperature; and

reacting said single component at the second predetermined temperature to form a surrounding layer.

2. The method of claim 1, wherein the single component is an uretdione or blocked isocyanate material.

3. The method of claim 1, wherein the step of providing the single component comprises the step of combining isocyanate with an amine or poloyl.

4. The method of claim 1, wherein the second predetermined temperature is in the range of about 150 to about 180°

C.

5. The method of claim 1, wherein the second predetermined temperature is in the range of about 140 to about 180°

C.

6. The method of claim 1, wherein the portion is an intermediate layer.

7. The method of claim 6, wherein the intermediate layer is a vapor barrier layer.

8. The method of claim 1, wherein the portion is a cover.

9. The method of claim 8, wherein the cover is a vapor barrier layer.

10. The method of claim 1, wherein the portion is a core.

11. A method of casting a portion of a golf ball comprising the steps of:

grinding a uretdione having a first predetermined temperature at which the uretdione is blocked;

dispersing the ground uretdione in a liquid of polyol or polyamine;

combining with at least one catalyst to create a slurry; and

pouring the slurry into a mold and heating the mold to a second predetermined temperature sufficient to cause the uretdione to become unblocked, the second temperature being higher than the first predetermined temperature, to form a surrounding layer.

12. A method of casting a portion of a golf ball comprising the steps of:

providing a single component comprising 3,5 diemethylpyrazole blocked-IPOI that is blocked and stable at a first predetermined temperature and becomes unblocked at a second predetermined temperature, wherein said second predetermined temperature is higher than the first predetermined temperature;

grinding 3,5 dimethylpyrazole blocked-IPDI;

dispersing the ground 3,5 dimethylpyrazole blocked-IPDI in a liquid of polyol or polyamine;

combining with at least one catalyst to create a slurry;

pouring the slurry into a mold and heating the mold to the second predetermined temperature; and

reacting said single component at the second predetermined temperature to form a surrounding layer.
