Appl. No.:

16/982188

Inventors:

- Wickliffe OH, US
Kevin J. Hughes - Sammamish WA, US
Elizabeth A. Schiferl - St. Paul MN, US
David M. Nickerson - Concord Twp OH, US
Alonzo Smith - Bedford OH, US

International Classification:

C10M 147/04
C10M 169/04

Abstract:

There is disclosed an antifoam component for a mechanical device which includes a poly(acrylate) copolymer. The antifoam component has improved foam performance in finished fluids utilizing dibutyl hydrogen phosphite compounds, such as driveline fluids. A lubricating composition comprising a) at least one oil of lubricating viscosity; and b) an antifoam component comprising a poly(acrylate) copolymer. The poly(acrylate) copolymer, b) may include (i) from about 30 wt % up to about 99 wt % of a (meth)acrylate monomer having Cto Calkyl esters of (meth)acrylic acid; and (ii) from about 1 wt % up to about 70 wt % of a fluorinated (meth)acrylate monomer.
