ABSTRACT:
The present invention relates to an electroviscous fluid comprising the dispersion in an electrical insulating fluid of an organopolysiloxane having at least one metal sulfonate group in its molecule. The electroviscous fluid of the present invention can further comprise a polyether. The electroviscous fluid of the present invention does not wear or abrade surrounding equipment, is thermally stable, and that has a large electroviscous effect (yield value) and an excellent dispersion stability.
