Abstract
A magnetorheological fluid composition comprising magnetosolid particles, magnetosoft particles, a stabilizer, and a carrying fluid comprising an aromatic alcohol, a vinyl ester, and an organic solvent or diluent carrier such as kerosene, in proportions sufficient to provide substantially no agglomeration or sedimentation of magnetic particles over temperatures of from about -50.degree. to 120.degree. C. The composition can be made by preparing a carrying fluid comprising a vinyl ester, an aromatic alcohol and kerosene; preparing a first carrying fluid composition comprising magnetosoft particles, a stabilizer and a first sample of the carrying fluid; preparing a second carrying fluid composition comprising magnetosolid particles and a second sample of the carrying fluid; and admixing the first carrying fluid composition and the second carrying fluid composition.
