  • Viscous liquid vibration damping composition
    Patent number: 6787057
    Abstract: A viscous liquid vibration damping composition containing (A) 30-95 weight percent of a viscous liquid, and (B) 5-70 weight percent of at least two solid powders having different average particle diameters, where the difference between the respective average particle diameters of the two solid powders is at least 10 &mgr;m. These viscous liquid vibration damping compositions are superior in vibration damping properties, and possess a stable vibration damping characteristic that is not significantly affected by temperature changes.
