Abstract

A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a cover comprising a thermoplastic polyurethane material and a dendritic polymer in a solution containing an isocyanate functionality reactive material. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing.

Claims (10)

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 an isocyanate in an amount of 2.16% by weight of the solution, 1.5% by weight of a dendritic polymer and a solvent;

removing the solution covered golf ball precursor product from the solution;

air drying the solution covered golf ball precursor product at approximately 72° F. to create an dried solution covered golf ball precursor product;

placing the dried solution covered golf ball precursor product in a second solution comprising an isocyanate in an amount of 2.16% by weight of the solution, 1.5% by weight of a dendritic polymer and a solvent to create a second solution covered golf ball precursor product; and

heating the second solution covered golf ball precursor product to create a final golf ball precursor product.

2. The method according to claim 1 wherein the golf ball precursor product is placed in the solution for one to two minutes.

3. The method according to claim 1 wherein the second solution covered golf ball precursor product is heated from two to four hours at a temperature ranging from 125° F. to 250° F.
