Abstract
Lubricating compositions are described, the lubricating compositions comprising a base oil component and an additive component, wherein the additive component comprises a non-silicone anti-foaming agent.
Claims24
A lubricating composition, comprising:
- (A) a base oil component, comprising:
- a polyalphaolefin (“PAO”), a mineral oil, or both, and comprising from about 95% to about 99.5% w/w of the lubricating composition;
- and
- (B) an additive component, consisting essentially of:
- (1) an anti-wear agent selected from the group consisting of:
- a C3-C6 alkylated triarylphosphate, a C4-C18 alkyl phosphate, a diarylether phosphate ester, a diarylether phosphate diester diphosphate, or a mixture thereof,
- (2) an aryl amine antioxidant agent selected from the group consisting of a phenyl alpha naphthyl amine, alkylated phenyl alpha naphthyl amine, or a mixture thereof,
- (3) a metal deactivating agent comprising a tolyl triazole derivative,
- (4) an anti-rust agent selected from the group consisting of an alkyl succinic acid ester, an alkenyl succinic acid ester, or a mixture thereof, and, optionally,
- (5) a soluble red dye, and,
- (6) a non-silicone anti-foaming agent comprising an acrylate and/or a polyacrylate, wherein the acrylate and/or polyacrylate consists of one or more non-fluorinated acrylate and/or one or more non-fluorinated polyacrylate,
- wherein, the additive component comprises from about 0.5% to about 5% w/w of the lubricating composition.
