Abstract
An improved process and resultant composition for covering golf balls with polyurethane is disclosed. Either the prepolymers or the curing agents are selected to have different rates of reaction so that a partial cure can be made to form a ball half shell whereafter the half shell can be disposed about the golf ball core and finished cured.
