Abstract:
1. A process for improving adhesion strength between a first surface and a second surface of a golf ball comprising: roughening at least a first surface of the golf ball to create a roughened first surface with a surface finish in the range of 0.5 μin. to 2000 μin.; chlorinating the roughened first surface of the golf ball by immersing the roughened first surface in a liquid solution containing free chlorine to create a chlorinated roughened first surface; rinsing the chlorinated roughened first surface of the golf ball; drying the chlorinated roughened first surface of the golf ball to create a dried chlorinated roughened first surface; dipping the dried chlorinated roughened first surface of the golf ball in a solution of 2% by weight of a water-borne silsesquioxane oligomer to create a treated first surface of the golf ball; drying the treated first surface of the golf ball; and joining the second surface of the golf ball to the treated first surface of the golf ball.
