GOLF BALLS WITH OXYGEN AND MOISTURE BLOCKING PROTECTIVE PAINT LAYER

摘要

The present invention relates to compositions for golf equipment that can be applied as a thin paint layer to block oxygen and moisture from underlying structural layers. The compositions include a polymer component present in a resin system, a stabilizing component, and porous particles.

主权项

1. A golf ball comprising a core and a cover, wherein at least one paint layer is disposed about the cover, wherein the paint layer is formed from a composition comprising:
a polymer component; a paste comprising porous particles and a stabilizing component, wherein the porous particles have an average diameter between about 100 μm and about 500 μm, wherein the stabilizing component comprises a symmetrical copolymer comprising two alkylene oxide blocks having the same chain length surrounding an alkylene oxide block, wherein the paint layer has a thickness of about 100 μm to about 500 μm, and wherein the golf ball has a weight gain of about 15 grams per 100 in2 per day or less at 38° C. and 90 percent relative humidity.
