Abstract
The present invention is directed towards a golf ball wherein at least one portion of the golf ball is formed from a staged resin film that may contain fillers or additives to alter the physical or chemical characteristics of the ball, such as its weight distribution, its moment of inertia, and its moisture transmission properties. The invention also relates to methods of forming a golf ball having a portion formed from a staged resin film.
Claims17
A method of making a golf ball comprising:
- partially curing a crosslinkable resin to form a staged resin film;
- sandwiching the staged resin film between two layers of polybutadiene-based material to form a laminate;
- applying the laminate to a core.
A method of making a golf ball component comprising:
- partially curing a crosslinkable resin to form a staged resin film having a Shore D hardness that is about 10 percent to about 80 percent of a completely cured staged resin film, wherein the crosslinkable resin comprises a partially or totally blocked isocyanate, an interpenetrating polymer network, an isocyanate compound comprising a ketimine, or mixtures thereof;
- forming a portion of the golf ball with the staged resin film.
A method of making a golf ball component comprising:
- partially curing a crosslinkable resin to form a staged resin film having a tensile strength that is about 10 percent to about 80 percent of a completely cured staged resin film, wherein the staged resin film comprises at least one of a partially or totally blocked isocyanate, an interpenetrating polymer network, an isocyanate compound comprising a ketimine, or mixtures thereof;
- and
- molding a portion of the golf ball with the staged resin film.
