ELECTROVISCOUS FLUID

摘要

PURPOSE:To improve electroviscous effects of an electroviscous fluid using fine powder of a quaternary ammonium salt group-containing silicone resin and further improve settling and redispersibility of a disperse phase. CONSTITUTION:An electroviscous fluid is characterized as follows. The aforementioned fluid is composed of 1-60wt.% fine powder of a quaternary ammonium salt group-containing silicone resin, containing 0.1-20wt.% moisture and having 0.05-100mum average particle diameter and 99-40wt.% fluorosilicone oil having 5-1000cSt viscosity at 25 deg.C.
