Disclosed are coating compositions suitable for application to polymeric substrates. The coating compositions include: (a) a film-forming resin; (b) a non-volatile chemical etchant; and (c) a solubilizing agent.

Coating compositions and methods for improving the adhesion of coatings to polymeric substrates

A resin containing a liquid pigment dispersion is disclosed. The dispersion comprises a pigment dispersed in a blend of two or more active hydrogen-containing materials that together have a freezing point that is room temperature or below. The pigment remains dispersed in the blend, even if the dispersion is subjected to freezing and thawing. A curative blend comprising at least two active hydrogen-containing materials, which is liquid at room temperature, is also disclosed. The dispersions and curative blends of the present invention can be solvent-free. Resins and prepolymers comprising the curative blends of the invention, either pigmented or unpigmented, are also disclosed.

Liquid pigment dispersion and curative agents

A method of forming golf balls with at least a portion formed from polyurethane and polyurea compositions employing a curative blend that includes a pigment, a curing agent, and a compatible freezing point depressing agent so that the curative blend has a lower freezing point than the curing agent by itself and the blend does not lose pigment dispersion upon solidification and subsequent thawing.

Polyurethane compositions for golf balls

A liquid pigment dispersion is disclosed. The dispersion comprises a pigment dispersed in a blend of two or more active hydrogen-containing materials that together have a freezing point that is room temperature or below. The pigment remains dispersed in the blend, even if the dispersion is subjected to freezing and thawing. A curative blend comprising at least two active hydrogen-containing materials, which is liquid at room temperature, is also disclosed. The dispersions and curative blends of the present invention can be solvent-free. Resins and prepolymers comprising the curative blends of the invention, either pigmented or unpigmented, are also disclosed.

The present invention is directed to curable film-forming compositions comprising:

Curable film-forming compositions demonstrating self-healing properties

Polyurethane and polyurea compositions for golf balls with improved stability of the curative blend, wherein the curative blend includes a pigment, a curing agent, and a compatible freezing point depressing agent so that the curative blend has a lower freezing point than the curing agent by itself and the blend does not lose pigment dispersion upon solidification and subsequent thawing.

Polyurethane and polyurea compositions for golf balls

A golf ball comprising a core, a barrier layer enveloping the core, and a cover enveloping the barrier layer, wherein the barrier layer has a moisture vapor transmission rate less than that of the cover, and the barrier layer comprises a thermoplastic or thermoset composition of microparticles dispersed in a binder.

Golf ball with vapor barrier layer and method of making same

The present invention provides an adhesion promoting agent which includes a graft copolymer formed by a halogenated polyolefin polymer with at least one reactive functionality and a substantially saturated hydrocarbon polymer having more than one reactive functionality. At least one reactive functionality of the saturated hydrocarbon polymer is reactive with the reactive functionality of the halogenated polyolefin to form the graft copolymer of the invention.

Adhesion promoting agent and coating compositions for polymeric substrates

The present invention provides coating compositions including: (a) about 75 to about 99.9 weight percent of a crosslinkable film-forming system including one or more crosslinkable film-forming resins and one or more crosslinking materials which is capable of reacting with the film-forming resin to form a crosslinked film; and (b) one or more substantially saturated, predominantly hydrocarbon adhesion promoting agents having an average of more than one pendant or terminal polar group per molecule which are capable of reacting with the crosslinking material, the adhesion promoting agent(s) being present in an amount ranging from about 0.1 to about 25 weight percent on a basis of total resin solids of the coating composition. The coating compositions are useful for directly coating surfaces of thermoplastic and thermosetting plastic substrates, such as TPO and RIM, without the aid of flame or corona pretreatment, or the use of an adhesion promoter. Plastic articles coated with the coating compositions are also disclosed.
