Abstract
A coated rubber composition includes a rubber composition coated with a liquid refresh agent selected from the group consisting of one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, C9-C15 aliphatics, C9-C15 cycloaliphatics, ethyl lactate, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof. A method of application and a coated rubber composition are also disclosed.
Claims19
A coated rubber composition comprising a rubber composition and a coating, wherein the coating is a liquid refresh agent 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;
- wherein the coating has an evaporation rate of about 0.1 mg/min to about 8 mg/min at 25° C. and 1 atm pressure;
- wherein the rubber composition comprises wax and a rubber polymer with a polydispersity (Mw/Mn) of about 1.5 to about 6.0;
- wherein the rubber composition is uncured.
An article of manufacture comprising:
- a first uncured rubber component comprising an elastomer selected from the group consisting of:
- polychloroprene, butyl rubber, hevea and non-hevea natural rubber, polyisoprene, polybutadiene, nitrile rubber, poly(isoprene-styrene), poly(isoprene-butadiene), poly(styrene-butadiene), terpolymers of isoprene, styrene, and butadiene, and combinations thereof, the first uncured rubber component having a polydispersity (Mw/Mn) of about 1.5 to about 6;
- a wax;
- the first uncured rubber component including a first coated surface, the first coated surface coated with an organic liquid having the following characteristics:
- an evaporation rate of about 0.1 mg/min to about 8 mg/min at 25° C. and 1 atm pressure;
- and a flash point of about 30° C. to about 100° C., and wherein the organic liquid is 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.
