1. A method comprising the steps of:
applying an effective amount of a refresh agent to a surface of a first uncured rubber component, the refresh agent including a liquid selected from the group consisting of: one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, dodecane, decane, undecane, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof, thereby forming a first coated surface; and
joining a second uncured rubber component to the first coated surface of the first uncured rubber component at an interface;
wherein the amount is effective to temporarily refresh tack of the first uncured rubber component and hold it to the second uncured rubber component until curing;
curing the joined rubber components to form a vulcanized rubber article;
prior to or during curing, the refresh agent evaporating or eluting from the joined rubber components;
wherein the refresh agent has an evaporation rate of about 0.1 mg/min to about 8 mg/min at 25° C. and 1 atm pressure;
wherein the vulcanized rubber article is free of or essentially free of the refresh agent.
