Abstract:
1. A method of forming a golf ball, the method comprising: placing a golf ball precursor product in a solution to create a solution covered golf ball precursor product, the golf ball precursor product comprising a cover comprising a thermoplastic polyurethane material, the solution comprising one or more chemical moieties capable of reacting with isocyanate functionalities, wherein the one or more chemical moieties capable of reacting with isocyanate functionalities is selected from the group consisting of polyester-based polyols, diamines, polybutadiene based polyols, polyamines, diacids, polyacids and mixtures thereof; removing the solution covered golf ball precursor product from the solution; heating the solution covered golf ball precursor product to remove the solvent to create a pre-treated solution covered golf ball precursor product; placing the pre-treated solution covered golf ball precursor product in an isocyanate solution to create a isocyanate solution covered golf ball precursor product; and heating the isocyanate solution covered golf ball precursor product to create a final golf ball precursor product.
