摘要：
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 C 1 to C 4 alkyl esters of (meth)acrylic acid; and (ii) from about 1 wt% up to about 70 wt% of a fluorinated (meth)acrylate monomer.
