摘要:
The present invention is directed to a golf ball that contains an interpenetrating polymer network, or IPN, including at least two polymeric components. These IPNs may be present in any golf ball layer, although in an intermediate or cover layer in one preferred embodiment. The present invention is also directed to methods of forming a golf ball containing an IPN in one or more of the layers.

摘要:
A golf ball including a center, a cover, and, optionally, at least one intermediate layer disposed between the center and the cover, wherein the cover is formed from a polyurethane composition, or a reaction product thereof, including at least one polyol; at least one polyisocyanate; at least one curing agent; and at least one color stabilizer; wherein the color stabilizer is present in an amount sufficient to provide a ΔC* of less than about 22 upon exposure to UV light over a timeframe of 1 hour.
摘要:
A golf ball with at least one moisture vapor barrier layer is disclosed. The moisture vapor barrier layer comprises an elastomer, and has a moisture vapor transmission rate of less than about 0.6 grams·mm/m2·day.
摘要:
Ultraviolet radiation curing of inks on game balls, golf balls and the like is disclosed. Production inks, logo inks and methods for forming production prints and logos on golf balls, game balls and the like are disclosed. To form an ultraviolet radiation curable water-insoluble production ink, at least an adhesion promoting component is added to an ink base. The adhesion promoting component is selected from the group consisting of a carboxylic acid functional monomer, a carboxylic acid functional oligomer, an ester functional monomer, an ester functional oligomer and mixtures thereof, the adhesion promoting component having at least one adhesion promoting functional moiety comprising at least about 2 moles of a carbonyl functionality per mole of the adhesion promoting component and being sufficient to maintain adhesion of the production ink of at least about 75% of the inked surface to the topcoat and to the surface of the game ball or the golf ball after ultraviolet radiation curing and after coating the production ink with the topcoat. To form an ultraviolet radiation curable water-insoluble logo ink, at least a toughening agent is added to an ink base. The toughening agent is sufficient to maintain adhesion of the logo ink to the topcoat of at least about 75% of the inked surface after ultraviolet radiation curing.
摘要:
A polyurea-based curable coating for use with sports equipment, such as golf balls, golf shoes, golf clubs, footballs, billiard balls, baseballs, and the like, of which the coating may be cured over time, with heat, or a combination thereof, providing enhanced adhesion to equipment surfaces, improved abrasion resistance, and increased water resistance.
摘要:
A golf ball with at least one moisture vapor barrier layer is disclosed. The moisture vapor barrier layer is formed from a composition comprising a filler dispersed in a liquid or solven-born polymer of multi-olefin, iso-olefin, or a combination thereof.
摘要:
A golf ball comprising a core, a cover encasing the core, at least one coating layer encasing the cover, and at least one indicia layer immediate adjacent to the coating layer is provided. At least one of the indicia and coating layers comprises at least one two-part, reactive composition comprising at least one radiation-curable iso(thio)cyanate and at least one isocyanate-reactive chemical.
摘要:
A method for increasing adhesion between golf ball layers comprising the steps of providing a golf ball layer having a first surface; preparing the first surface for treatment; exposing the first layer to a silane; providing a second golf ball layer; and adhering the second layer to the first via the silane. Additionally, a golf ball including an inner component, a molecular monolayer, and at least one cover layer, wherein the inner component and the at least one cover layer have differing surface energies and the cover layer is adhered to inner component with the molecular monolayer.
摘要:
A golf ball comprising a core and a cover, wherein at least one of the core and the cover is formed of a composition comprising an organic, inorganic, or metallic nanoparticulate material having a particle size of less than about 1000 nm and at least one matrix material.
