Abstract
The present invention is directed towards golf balls comprising a core, a cover and a coating composition layer, wherein the coating composition layer comprises a fluorinated polyurethane. The novel fluorinated polyurethane coating composition of the present invention enhance a variety of properties such as enhanced abrasion, impact and weathering resistance as compared to golf balls with conventional coating composition. Additionally, the presently claimed fluorinated polyurethane coatings also decrease the coefficient of friction of the surface of the golf ball, resulting in a modification of the spin rate when struck with a golf club and superior cleaning characteristics.
Claims23
A golf ball comprising a core, a cover and a coating composition layer deposited upon at least a portion of an outer surface of said cover, said coating composition layer comprising of a fluorinated polyurethane resin and a particulate material which comprises a plurality of poly(tetrafluoroethylene) particles.
A golf ball comprising a core and a cover and having a coating composition layer deposited upon an outer surface of said cover, said coating composition layer formed by a process comprising:
- (a) dissolving a fluorinated polyol in a solvent;
- (b) reacting said polyol with a polyisocyanate to form a urethane reaction product;
- (c) adding a particulate material which comprises a plurality of poly(tetrafluoroethylene) particles to the reaction product;
- (d) applying the reaction product to the surface of the golf ball.
A golf ball comprising:
- a core;
- a cover;
- at least one layer of a primer material deposited upon an outer surface of said cover;
- and
- at least one top coat layer deposited upon said primer, said topcoat material comprising a fluorinated polyurethane resin and a particulate material which comprises a plurality of poly(tetrafluoroethylene) particles.
A method for making a coated golf ball comprising:
- forming a golf ball comprising a core and a cover;
- and
- depositing upon at least a portion of an outer surface of said cover a coating composition formed by:
- (a) dissolving a fluorinated polyol in a solvent
- (b) reacting said polyol with a polyisocyanate to form a urethane reaction product;
- (c) adding a particulate material which comprises a plurality of poly(tetrafluoroethylene) particles to the reaction product.
