ABSTRACT:
A MR fluid formulation based upon a silicone liquid vehicle thickened with a treated fumed metal oxide and doped with one or more chemicals having hydrogen-bonding capability for use with natural rubber mounts. The MR fluid is resistant to settling of the magnetizable particles upon contact of the fluid with natural rubber. In one exemplary embodiment, the doping chemical is one or a combination of propylene glycol and a bifunctional ethoxylated amine.
