Golf balls incorporating at least one thermoset and/or thermoplastic layer/coating/film via reactive spray
Abstract
A method of forming a golf ball comprising at least one layer consisting of at least one of a thermoset or thermoplastic composition comprising the steps of: providing a subassembly having at least one of an innermost surface or an outermost surface; providing at least one polymeric mixture Pc comprising a plurality of particles having a softening, melting and/or reacting temperature Mp; heating a fluid with a heat source that does not contact Pc to a temperature Mph wherein Mp≦Mph to form a heated fluid; softening, melting and/or reacting the plurality of particles by mixing each polymeric mixture Pc with at least one heated fluid and forming at least one heated mixture Pcs; and propelling each Pcs onto at least one of the innermost surface or the outermost surface to form a thermoset and/or thermoplastic layer Tmpl about the outermost surface which may be comprised of a heterogeneous composition. The thickness of Tmpl may be from about 3 mils to about 0.10 in.
