Zusammenfassung:	A curative blend for a thermosetting polyurethane material that allows for a polyurethane material with greater durability is disclosed herein. The curative blend is composed of 4,4'-methylenebis-(2,6-diethyl)-aniline and a second curing agent. A preferred polyurethane prepolymer is a polytetramethylene ether glycol terminated 4,4'-dicyclohexyl methane diisocyanate polyurethane prepolymer. The thermosetting polyurethane is preferably utilized as a cover for a golf ball. The cover is preferably formed over a core and boundary layer.
