EASILY DISPERSIBLE ELECTROVISCOUS FLUID

摘要

PURPOSE:To obtain the title fluid having little particle sedimentation and being easily redispersible event if sedimentation occurs by dispersing each specified main ingredient particles and fine particles in an electrical insulating liq. CONSTITUTION:The title fluid is prepared by dispersing main ingredient particles (e.g. silica particles) with a mean particle diameter of 1-100mum and 1.0-10vol.% fine particles (e.g. silica particles) with a means particle diameter of 0.005mum or larger and smaller than 0.3mum in an electrical insulating liq. (e.g. dimethylsilicone).
