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.
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.
