Claim:
1. A method for forming a cover for a golf ball, the method comprising: dry blending a polyisocyanate crosslinker in a masterbatch with a base thermoplastic polyurethane material to form an injection molding material, wherein the composition by weight of the polyisocyanate crosslinker ranges from 17 percent to 27 percent of the injection molding material and wherein the composition by weight of the base thermoplastic polyurethane ranges from 63 percent to 73 percent of the injection molding material; injection molding a cover for a golf ball from the injection molding material; dipping the golf ball in a catalyst solution wherein the catalyst solution comprises an organometallic compound, wherein the catalyst solution is allowed to absorb into the cover for the golf ball; and heating the golf ball to allow continued diffusion of the catalyst solution into the cover for the golf ball.
