Problems solved by technology

[0011] A disadvantage of using conventional isocyanate treatment methods is that they usually require an additional step during the manufacturing process and they will not be very cost effective
These additional steps can be time consuming and reduce processing efficiency

Embodiment Construction

[0024] This invention generally relates to golf balls having covers made from thermoplastic polyurethane (TPU) compositions. Various polyurethane primers and topcoats were applied to the polyurethane outer coating according to the invention. The invention also includes the final golf balls produced from the application of these coatings.

[0025]Golf balls having different configurations can be made in accordance with this invention. For example, golf balls can be manufactured in three-piece, four-piece and five-piece constructions with single or multiple layers of cover material. Representative examples of such golf ball configurations are provided and discussed further below. As used herein, the term "layer" generally refers to any spherical portion of a golf ball. More specifically, in one form, a two-piece golf ball is manufactured that includes a core and a surrounding cover. It is also possible to manufacture three-piece golf balls with a double core and a single cov...

Abstract

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to thethermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

Description

technical field [0001] This invention generally relates to golf balls having covers made from thermoplastic polyurethane compositions. The golf ball includes an inner core and a surrounding thermoplastic polyurethane cover. Multi-piece golf balls can be manufactured having an outer core, an inner cover, and a mid layer. The present invention includes a method of applying a polyurethane coating to the thermoplastic polyurethane coating. The invention also includes the formed balls. The resulting ball with the thermoplastic polyurethane cover and surface polyurethane coating has many beneficial physical and game performance properties. Background technique [0002] Both professional and amateur golfers use multi-piece solid golf balls today. Basically, a two-piece solid golf ball includes a solid inner core protected by an outer cover. The inner core is made of natural or synthetic rubber such as polybutadiene, styrene butadiene or polyisoprene. The cladding surrounds th...
