Abstract
The present invention is directed towards a golf ball comprising a core, a cover and a protective clear coat layer, wherein the clear coat layer comprises a polyorgano-siloxane polymer. The novel clear coat compositions of the present invention are believed to provide enhanced abrasion resistance, impact resistance, and chemical resistance as well as diminished photodecomposition and increased adhesion. Optionally, the golf balls of the present invention may also employ at least one primer layer disposed between the cover and clear coat layer to improve the adhesion and physical properties of the polyorgano-siloxane clear coat compositions. Likewise, the present invention provides a method for producing the clear coat compositions of the present invention.
Claims18
A golf ball comprising a core, a cover and a clear coat layer, wherein said clear coat layer is the outermost layer and comprises at least about 10 percent by weight of a polyorgano-siloxane polymer.
A golf ball comprising a core, a cover, at least one primer layer and a clear coat layer, wherein said primer layer is disposed between the clear coat layer and the cover, and wherein said clear coat layer is the outermost layer and comprises at least about 10 percent by weight of a polyorgano-siloxane polymer.
A method for making a golf ball comprising a core, a cover and a clear coat layer wherein the clear coat layer is the outermost layer and comprises at least about 10 percent by weight of a polyorgano-siloxane polymer, wherein the polyorgano-siloxane polymer is formed by:
- (a) depositing a layer of a silane prepolymer on the outer surface of the golf ball;
- and
- (b) curing the silane propolymer to provide a higher molecular weight polyorgano-siloxane polymer.
