FIELD OF THE INVENTION
This invention relates to a vibration damping silicone composition, and in particular to a vibration damping silicone composition with excellent storage stability.
BACKGROUND OF THE INVENTION
Vibration damping compositions containing silicone oils and solid powders are known. For example, a vibration damping composition containing silicone oil and a powdered solid such as powdered silica, powdered glass, or powdered silicone resin, is shown in Japanese Patent Application Publication No. Sho 63-308241(Kokai). A vibration damping composition containing silicone oil and a powdered organic resin such as an acrylic resin having a glass transition point within the use temperature, is shown in Japanese Patent Application Publication No. Sho 63-308242(Kokai). However, these vibration damping compositions have poor storage stability or result in oil separation when stored for extended periods.
BRIEF SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a vibration damping silicone composition offering excellent damping of vibration and storage stability.
These and other features of the invention will become apparent from a consideration of the detailed description.
