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.
Claims13
A lubricating composition, consisting essentially of:
- between about 98.75% w/w and about 98.8% w/w of a base oil component, consisting essentially of:
- a polyalphaolefin (“PAO”) having a kinematic viscosity of about 6 centiStokes at 100° C.;
- and
- an additive component, consisting essentially of:
- between about 0.05% w/w and about 0.10% w/w of a non-silicone anti-foaming agent comprising a polyacrylate polymer,
- about 0.05% w/w of 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, and mixtures thereof,
- about 1.0% w/w of an aryl amine antioxidant agent,
- about 0.05% w/w of a metal deactivating agent, and
- about 0.05% w/w of an anti-rust agent.

The A lubricating composition, comprising:
- a base oil component, wherein the base oil component comprises:
- a first mineral oil having a kinematic viscosity of about 11 to about 13 centiStokes at 100° C.;
- and
- a second mineral oil having a kinematic viscosity of about 4 to about 5 centiStokes at 100° C.;
- and
- an additive component, wherein the additive component consists essentially of:
- 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;
- 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;
- a metal deactivating agent comprising a tolyl triazole derivative;
- 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
- a non-silicone anti-foaming agent comprising a polyacrylate polymer.
